what different types of ports are there?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.
