I was going to do the hybrid cause it seems easier for me to get more performance without doing much head work. I am probably wrong but like I said I started to get a little confused with all of the stuff I was reading.

I thought that there was a lot of head work involved to get the oval port to fight right.


A hybrid takes exponentially more work & money to match the results of a simple straight oval port setup.
Machining for 3L valves, port work to suport 3L valves, chamber shaping to match 3L bore, then there is the actual indepth port work itself. I'm not saying the price is not justified because that is a TON of labor. I am saying the end results are hard to justify though!

Most simple "straight" hybrids are about 185-195 FWHP while oval ports are ~202-208FWP.

Even the full ported hybrids normally only match up with the straight oval ports. There are of course a couple "top end" ($$$) hybrids that are 210's.

For ref - All numbers are with SVT cams.


The port shaping of the oval port inlets to the split port LIM is not hard to do. I have some very good step by step pictures on my site.
If you search you can also find countless pages of information about it as well.
