I recently purchased a black 98 SVT with a blown engine. Between the guy selling it and what I've see i would guess i has a spun bearing. It still has all its oil and knocks badly while running. I only looked at the car once and was not able to hear it run myself. Not that it really matters i want the car either way, and the less it runs the less chance for more damage. My questions is what dammage should i expect on the heads? I know it is a interfearence head so im sure at least the valves are bent, but can it cause dammage to the head casting, valve guides, cams etc as well? I plan on replacing the valves anyways with 3L units. Any expierence or theories are apprciated!
P.s. Search Phycos go easy, i found some mention of it but not much detail.

If the bottom end is making the noise, then the heads should be fine... unless the bearings are totally gone out of the rods, to where the pistons would hit the head that is. Most spun bearings come at the price of severe "walking" of the other bearings that didn't spin, including the mains... some of which may have actually spun too. Once you get the oil pan off, you can see which rod bearing went by moving the rod around with your hand, or by gently tapping the rod caps with a small hammer to find the one/ones that don't sound solid. To find the condition of the mains, the whole bottom end will have to come off.
Since you're posting in the 3L forum, I assume you're thinking about a 3L swap then? My advice, inspect then sell the SVT heads for some dough, keep the SVT cams and put them in the 3L oval port heads from a 2001+ 3L from an Escape/Tribute and do a full 3L swap.

Are the escape heads that much better than the 2.5L heads? Do they offer more flow/power? I was under the impression that the 2.5L heads would result in a better hp increas. Please set me straight on this issue.

2.5L (i.e. hybrid) offers a greater CR. (~11.24 straight swap no chamber work)
However you can't get any real timing on pump gas (92-93 octane) so it's not as big of a perk as it could be. To be honest it can actually be detrimental "comparatively" because a lower CR engine can run optimum MBT.
The oval (tumble) port heads are significantly superior to the split port heads.
Flow bench results alone show bone stock oval ports flow nearly what full ported split port heads do.
Then add in the fact the tumble design promotes much greater cylinder filling & fuel atomization and you see why even basic oval port engines are dynoing just like all out ported hybrid engines.
Better design, more efficient heads beats higher CR and porting on pump gas. It's also $$$$ cheaper to boot.
Price porting heads and adding 3L valves & seats once.  The labor is killer and the price per hour is very legit. It is Extremely time consuming!

Yes, but those of us with skills do manage a good P&P job don't we! 
OF course, I've made life easier with my oval port heads too but hey.... My stuff was the sh|t!
Do as he says, swap in an oval port 3L and it will be very satisfying for you.

What kind of HP do you all expect on a mildly tuned full 3L with SVT cams?

oval or split port? 3.0L intakes as well?

Oval with 3L intakes. This is my setup which dynoed at 180.5hp @ ~6250 and 178.5ftlbs @ ~4500. I'd post the dyno plot if I knew how.

Ouch!
Sounds like you have other issues.
My 2.5L put down 190's and 170's.
An SVT 3L oval port should be around 200/190.

Could have been a Mustang Dyno...
You should know better than to compare #'s from different Dynos...

Now that I have a couple of thousand miles on the motor, I'll be going back to the dyno (probably a mustang dyno here in the DFW area) to get another baseline. Dyno Dave's did my original tune.
I really wanted to see how my numbers compared to other N/A full 3L's. Also, I'm getting about 20MPG (mostly highway driving) which is worse than what I thought it ought to be.

Dyno Dave's in Michigan? And 20mpg?!?!? There's definitely some issues. What injectors are you running? What MAF? I actually get better MPG with my 3.0L than I did with the 2.5L..

Have you checked all of your injectors? I assume 19# injectors correct? You could possibly have an injector stuck open, or even a small fuel leak(probably not the case).

19# injectors. I haven't checked anything and it's really because the engine runs fine, pulls hard and hasn't exhibited any problems. Once I get another dyno with an A/F plot, then I might make some changes.

Do all 2001+ taurus, sable duratecs have oval port heads as well? You only mention the escape heads. The plan so far is 3l oval port heads (Im going to attempt a DIY port job as well) SVT cams, SVT Upper and Lower IM and then do some more research on 19 vs 24lb/hour injectors and MAF to match. I will have all the parts available to me from the two engines, i just want to make sure i have the best combination.

Yes they will have the oval port heads. But that is not the main issue. The Escape has the revised oil pan where as I believe the taurus/sable does not. Also, the escape motor can accomodate a cam driven water pump where as the taurus/sable motor will need an EWP..

Was you 2.5L tuned?
Is your 3L tuned?
I get slightly lower MPG with the 3L. Roughly 1 mpg "comparatively" so it's minimal and my driving is a lot more city now so that means a lot more ZOOM ZOOM.
The 2.5L was 23-25mpg in mixed and 28-30 on the highway
The 3L is 21-23mpg in mixed (more city though) and 27-28mpg on the highway.
As you all know my foot is lead and redline is my friend so I have always been pleased with the mileage I could tune out of the Duratec. High efficiency in all stages of operation.

Not true.
All 01+ standard 3 liters are oval port with the cam driven W/P.

Ahh thank you for clearing that up.. I was on the verge of not entering that post as I thought that was the case. And now that I think about it, I'm a retard as my 2000 Taurus 3L was an oval port and well, I have a cam driven w/p..
As for the MPG, neither of my motors were tuned.. The 2.5L had only Bassani and open K&N filter. The 3L has run strong and flawless since day 1. Been waiting until all mods are finished before tuning. But have seriously considered the Tweecer unit.
