I have been running stock heads that I ported but I just put on a set of Sportsman ll which should increase my HP and torque by 40-50. Next is a gear chage to 3:55 and should be able to get into the low 13's with it.Keep smiling, it only hurts when you think it does!

Eric My engine was bored to 315(not much bigger than stock) but a friend of mine who rebuids engines gave me a set of world sportsman heads with 190cc intake runners and 72cc fast burn chambers. He said they should work with my engine. I hope the hell there not to big because I really don't feel like changing heads again in my cold garage.Keep smiling, it only hurts when you think it does!

I don't know of any cylinder head company that makes a head that has a port volume of 190cc's.

Eric Your right. I was going to buy a set of AFR high torque cylinder heads which are rated at 190 cc, but got these for nothing except a trade for a set of 327 heads. They are 200 cc like you mentioned. Are they to big for my engine?Keep smiling, it only hurts when you think it does!

I wore a camouflage T-shirt once. The response in the pub was "Oooh, it's a floating head!" .
