Go with the SI2 cam and 64cc heads. Before even considering the 59cc I would want to know the piston to deck clearance. My LS2 was .005 out of the hole. This will help you: http://www.c5frc.com/calculators/Com...Calculator.htm

Question Piston out of the deck

its hard to tell how far the piston is over the deck , cause since the engine isnt warmed up , you can slightly move the head of the piston toward the top and bottom of the engine .. im guessing its about .005 to about .010 out

You check it on the intake side and exhaust side of the piston and divide by 2 for your average. The difference between .005 and .010 is huge. You want to make sure to be accurate.
