Head choices???? Thought i had it figured out and talked to knowledgable builder who highly recommends the Dart Pro series 225 with a 230ish 600 lift cam around a 110 LSA. what do you guys think? I know the casting is better than the 5.3 prc head i was considering with a torquer2 or 228R cam. but will it be lazy due to the bigger 225cc runners and the 62cc combustion chambers? The 5.3's have the 220cc runners and 59 cc chamber to boost compression and keep velocity up. Flow numbers are identical at 500 lift on respective websites but Dart doesn't publish 600 lift numbers. I have no doubt the Darts are better quality castings. This will of course go on a bolt on 346. A4 3600 stall. Any comments or thoughts are welcome. Too damn many decisions!! LOL

I would love AFR's! I can get a deal on these though. Anybody with with any real world experince or knowledge about these? Website says they flow about at 205 on the exhaust side at 500 lift which seems low to me but the intake side looks pretty good.
