they will work on your carbed motor just the same.

stock for stock the gtp's make more power, but with a little work the real gt40's make alot more power, they come stock with bigger valves and ports i believe. remember that youll need custom headers for the gtp's to work

the intake ports and valves are the same on the GT40's and the GT40P's, its the exhaust that is different. the 40's have the larger valve, and the P's have the standard sized exhaust but they have a slighty better ex port on them.really, the best way to go is to use the P's with 1.94/1.60's and blend everything after they are opened up for the larger valves.

What type of header will I have to get to fit. I have a friend that has a fresh pair that he gave me no charge. Now I just have to tear down the motor
