So you guys are a pretty convicing group. I'm taking the block and heads down to an Engine Rebuilder i know. Would really like to keep things pretty much stock, maybe a hyperutectic piston and of course new valves by what most people have said so far. I have a Crane Cam here with 216 duration intake 228 exhaust 524" lift intake and 519 exhaust. Just wondering about all this reading I've been doing on these 4V heads and how overkill they are for street cruising. Hey I like horsepower too but would the 2V heads be a better choice.
