Thanks for the info... good stuff. I thought 200cc runners were a bit much also.

Found a set of 64cc chamber, 192cc runners, for 1.6 and 2.02 valves. Aluminum heads..... these would probably be better, eh?

also for added info-I'm going to be running crane 1.5 roller tip rockers, Manley steetflo valves and I plan on running a lunati Voodoo cam 262/268 duration, .468/.489 Lift (in/ext) w/ Lunati hydraulic lifters and springs..

Thanks again.
