ok im getting ready to buy a set of brownfield /afr heads ....they are 215 cc runners..2.05/1.6.. 56cc heads...these are pretty big heads.....im going to be putting them on my 355....i was just wondering if my bottom end would be ok for it ....its fairly simple..bored .030 over....new but stock rods...and like 9.5/10.1 pistons....basically just a step over stock... i was told by some people these heads would work fine and other people said these heads would be to much for my bottom end....id rather just put em on and go....whats ur suggestions.....if i need to il be able to put on a set of speed pro 11:1 pistons.....and right now it has a .535 cam....but plan on getting up to .555

 

runner seem a little big, something lite a 355 with your lift would probaly benefit from something like a 200cc head, ive bought aa set of brodix IK200 heads, maybe look at RHS, the have a 200cc head with (i think) a 56 or 58cc chamber, 2.02/1.69 valves, and can be had fairly cheap
