I have been looking at these heads for awhile now. I was told by a couple of good engine builders to stay away from Trickflow, but the flow numbers for these heads are outstanding, especially on the exhaust side. It makes me wonder how accurate they really are. In any case, I have a 436 SBC, 400 .040" over 4" stroke In a street driven car that is N/A. Currently running a set of Brodix Track 1's with a good amount of work done to them. 11.7:1 comp, Edel 2925 intake, Bullet cam on a 112LSA with 247 and 256 dur @.050" and .610 lifts. Accel DFI system, Batch fire(OLD SCHOOL
) 1 3/4 Headers, 700R4 trans with 3k (VERY TIGHT) converter, and 3.5 ratio out back on 28" tires. Car runs A best of 11.35 @120 with a 1.52 60 I shift at 58-6K. I have spun it to 6500 but it didnt go any faster. It went 11.39 @120. So would these heads help me get 10.80's? I ran the numbers on some dyno's and on some proven perf calculators, and it said it would. Very intresting........ How are these heads holding up so far?? Any valve problems? Valve seats ok? Guides? Deck? How are the springs?

Are you talking about a street/strip 355 or would that be more of a strip only setup? I always thought that a 215cc head would be too big for most street/strip SBCs under 383". Do you think with the right cam and intake choices a 215cc head would work well on a 355" streetable engine with efi?
