Those heads will work, but you'd probably go faster with some small bore AFR 225 heads. I just got mine last week and plan on bolting them up this week. I'll find out soon if they're worth swapping for the AFR 205s.

hey thanks for the fast response is it true this cam can be installed with flycutting?
also if you have the specs can you pm me them? lg is no help and i own the damn thing...i bought this cam used with low mileage...also will i have to flycutt with these heads? what do you recommend in a 241,243,ect casting thats ported out? or should i just bite the bullet for 225cc or better heads(etp)? sprry for alll the questions i just sold a vehicle and have some cash to play with....what do you think of the dart 225cc ? like these...

I'd put Katech rod bolts on ur list if ur reving that high.

Is there a budget for these heads?

"Valves:
They come with brand new 1 piece stainless Ferrea 2.02" or 2.05" Intake valves and 1.60" Ferrea exhaust valves."

Larger than stock vavles = flycut with that big of a cam

gsxzo6

kind of a budget...this is just what i found and would give me decent comp ratio and they flow over 300 at .600 lift....what do you have in mind

BTW, the ballpark for the G5X4 cam specs are around 236/244-111+1 or 2. Around the size of a TSP MS3 but with a narrower LSA. It's a nasty cam, but a good one.

Those or the patriots I'm looking at with my big cam setup. I don't want to flycut.

I'm also interested in the new small bore AFR 225s, after talking to Matt at TTP, theyre not sure if theyre gonna have to flycut with cams of this size. Im thinking they will.

gsxzo6

i knew the basic specs and i know the lift is around .612 on the high side...do you guys think with those heads and this cam along with my mods ill be around 480+ wheel?

gsxzo6

if io have to flycut thats no biggie...but will the heads and cam support the 7100 redline? or should i just go to TEA and have them do my heads up(243 z06)?

If you dont mind flycutting and price isnt an issue go with proven AFR 225s or the new 11* ETP heads (which are back ordered)

gsxzo6

with 225cc afr's dont they only come in a large cc chamber? or did somehting new come out ? how much would i mill them to get about 11-1 compression? thanks for the quick replys guys keep them comming

gsxzo6

what about the patriot heads? ls6 stage 3's on a stock 3.9 bore?

what gaskets would i need to do this ?

if you mill the stock heads, or buy stock heads that are milled .050, you are gonna definitely have to flycut with a G5X4 cam. and more than likely you will have to go with 7.350 pushrods. the X4 cam clears stock, unmilled heads, but milling them and using aftermarket valves can create problems. make sure you check your piston to valve clearance before bolting everything up or you could have a major problem.

The S3 heads are recommended for larger than stock displacement

gsxzo6

hmm all right thanks for all the info...can i do rod bolts through the oil pan with the motor still in the car?(just take the pan off) also i think i may just go with cheaper all turnative...which is the patriot stage 2's with the smaller combustion chamber(i think 58cc or 59cc)....also THIS IS A BIG QUESTION...

what size pushrods would i need for the g5x4 on the patriot stage 2's with the smaller combustion chamber? i know stock unmilled id go with 7.4 of some kind.
thanks a lot
