which one would be better with 1.94/1.50 valves. i know 041 has higher compression but does it flow better. 350 sbc ,holley 4412, cast iron exhaust manifolds. 170 lbs. cranking compression max. isky 270 megacam. hobby stock 3400# nova.

The 041 is arguably the best non-vortec head there is. I'd go with it. Even if the flow is 'only' equal, the 1 - 1.5 point CR jump is worth about 5% power at all RPMS.
