Thanks DrEamer, only want to do this once and I have read lots of comments concerning the advantages of aluminium. Trick Flow does look like a good head but I have no experience with aluminum heads at all. Thanks for pointing me in the direction of that slippery slope.
Does anyone have any more facts concerning the EQ heads from Imm versus PIE's heads. Level 1 port job with pretty impressive flow #'s at PIE for $1500.
