well good luck finding 00R heads, mite be nearly impossible and super super super expensive. ur better off finding some termie heads, but honestly the "b" heads on ur cobra flow so much i doubt you'll pick up any horsepower swapping them. I got my heads raceported, and they are sposed to be good for at least 50hp gain. Sean Hyland Motorsports will port ur cobra intake manifold for 700 bucks and thats sposed to be good for another 50hp too, but when you port those things its only beneficial for boost so id consider throwin in a supercharger or turbo.

post this question in the 4V section and you'll get some great answers as well.

well Sean Hyland motorsports will port the intake for like 730.00 or something like that. it's in Canada. I had Houstan Performance port my heads. MMR in cali will port your intake as well. They dont make after market heads for CObra engines. you can swap like FR500's but they arent cost effective at all. Cobra heads already flow really really good, porting them makes them just that much better. But remember, doing a stage one port is ok, but if you do a raceport you neeeeed boost.

well theres like the stage one port, and thats just mild porting. i opted for the full raceport because i have a TT setup. if you're gona leave it N/A, do a stage one. if you're gona do boost and really reach for lota HP, do the raceport.
