I have narrowed down my choices for heads on my Hobby to 441's or 993's, which one would you go with?

I'm a thinking the 441's, but without the variables (additional rules/options),... it is tough to say Barney. More input please? Are you running IMCA Hobby rules?

if it ain't fun, then don't run

Thanks. They are not IMCA Hobby rules but a very close version of. We are going to run a 355 with a 500 lift cam on a rochester 2bbl. We run on a 1/4 mile banked dirt track. I am a motor dummy so I don't know much. Anymore advice?

I read somewhere that the 993's are almost identical to the 441's, the article stated that on some 993'2 they have the 441 cast into the water port on the underside of the they both have the same size valves?I guess I would go for the 441's there suppost to be a heavy duty casting not prone to crack........Jim
