call this company to talk to them about the heads since youre over seas


also talk to them about custom cams.... if your car has a stock intake which i doubt it does, they also offer a complete h/c/i package...

and i believe you want the 44cc heads....

someone correct me if im wrong, but the 44cc heads would have bigger chambers than 38cc therefore making them lower compression?

Correct. the first vid sounds like the car has a manual tranny in it almost. But also talk to fox lake too. They can hand port them and i've seen good gains from the port work they do on these heads.

If not ported 4v, then ported 3v (which is really better anyway) and youll be close to 300 cfm.

if hes going to the trouble of swapping to 4v heads, he should just buy a cobra and start off with a better platform...it doesnt appear to be a money issue


do you know what the trickflow heads flow? ported and unported?

Going off memory, unported is about 245 and ported is about 268. I dont necessarily agree its a better platform though, if this car was done right. But face it, if you really want a ***** out car, its almost always cheaper to do it yourself - at least if your hell bent on getting everything you want. The smart money is buying a clunker and doing all right from the beginning provided you have the time/skills/$, especially if the OP wants something crazy like over 800rwhp and intends to really race it.

(Claimed by TFS)
240 CFM @ 0.550” Intake
185 CFM @ 0.550" Exhaust

Some porters are claiming more cfm, but their technique and equip is in question. A 4v head with TONS of head work could hit 320 or so, but they cost $ and 4 cams. 3v heads can hit 280-290 cfm for less $ money than some PI or stock TFS heads. Also logan has that nice intake - that combo added to this car would probably be worth close to 100rwhp.

Fox lake ports them to 269cfm and i saw a baseline of a set of heads at 253cfm. But i think that he would want the 38cc combustion chamber because the 44cc chambers are for the guys with npi that want to just bolt the heads on without adding much compression...i think. i could be wrong about that one though. But about the 4v heads, Total Engine Airflow gets like 324cfm out of 03 cobra heads at .500 lift, 300 at .400 lift, and fox lake is getting right around there at .550 lift. If you get cobra r/ford gt heads, they are getting 350 intake and 300 exhaust ported from fox lake at .600 lift...which i dont know of any cams that aggressive for the 4v heads. Most ive seen of a 3v head ported is 287/223 from TEA. Thats not that much higher than the TFS ported, which is about $2500, versus needing to buy the 3v heads, and then having them ported...which is $1800 alone. 4v FTW all day every day. lol But since its already 2v, just get Trickflow heads and custom turbo cams and call it a day. And some body mods to make that thing look sick.
