Thanks! You are correct, the heads are stock. They will be the bottle neck until I get some nice aluminum heads later. I went ahead and ordered the Edelbrock Thunder AVS 800 and the Performer RPM intake. The cam is 244int/254exh 508/532 lift. Hopefully everything will work OK together until I can get the better heads. If not....I'll just have to explain to the wife that I "HAVE" to get new heads! That will probably work eh?
