Hey, guys. I'm a GT owner looking to do a 4v swap. Rather than just buy used stock parts, I'm looking into stage II Patriot 4v heads. Seems stage II is the highest I can find.

Anyway, I was wondering if anyone had Patriot heads on a 4v. The 2v ones I know are pretty decent, but all 2v heads flow like ****, except for the new Trickflows, that claim 240cfm intake. Still, that's not too good.

So here's my questions:

1. What does a stock 4v head (say a C head from a 99/01 Cobra) flow stock?

2. Does anyone have patriot stage II heads?

3. What do the patriot stage II heads flow?

4. Are the valves, springs, guides, etc... all upgraded to take high lift cams? Say stage 3 blower cams? Or are they just OE **** packed onto a ported head?

Thanks for any help. Not sure how active the SVT section is, but hopefully I'll get some quick replies.

I didn't think patriot ported 4v heads. At least when I bought some c heads from them on ebay about 3 weeks ago, they said they couldn't port them.

I've often wondered that myself. Patriot only going as high as stage 2. I have here my CJ Pony Parts Catalog and the springs and retainers are OEM. Says up to 70 cfm improvement. What ever up to is? They are $2345 the bare ones are $1945. I'd just get the bare ones so you can get the right stuff that will work together.

Mine flow better than those. But they are 03-04 heads. Better starting point to cnc from.
