Dion,

I'm sorry I jumped all over that post. It is actually very good to see some slightly different ways of making power. You guys may hit on something good there and I was trash talking it to quickly.
It looks like your combustion chambers weren't widened out as much as mine, they look a little smaller. If that is any guide you may have compression in the 10.3+ range, but surely not over 10.5:1.
I have to say that they did a nice job on the work, I just felt with the knowledge base that has accumulated over the last year and a half, it indicates that the 2.5L valves may limit the maximum potential of the motor.
Look at it this way though, you will have one hell of a platform for the vortech supercharger! That was another reason I was going with low compression in mine.
Good Luck,

I understand your frustrations, no harm/no foul. I know you're not happy with SHOshop, I know some people out here that aren't that happy with them either.
The chambers, from what I understand, were opened up to the gaskets. Which gaskets, I don't know, my assumption is they were opened up where you could see the gasket material stop on the heads (ie 2.5L gaskets). If it's limited by 2.5L valves, we'll find out in a month or so, after the car is broken in.
If the CR is indeed low enough, I may have to look into a Vortech as well. You've really peaked my interest in that option now....
One of the guys here, Jim Bandy, has over 9K on his SVT with an S/C, so I think the problems that Vortech encountered are almost over with.
