Cylinder head dyno shoot out
Overall, I can easily see 5-6 sets of SM heads being tested.
-ootb
-prepped
-basic ported
-high level ported
-cnc + prep
-bloomer
I can also see where the first 3 could be evaluated on a milder 360 type build where the basic ported heads landed you in the 450hp range.
Something with a true street type roller(like a Comp XR274R, 236/242-110).
If future plans called for the 408 short block and a 550hp type build for the higher level heads, then with the 360 perhaps unported oe 2.02 heads and some TF’s could round out that series.
-oe 202
-ootb SM
-prepped SM
-basic ported SM
