that`s a hard call, the 882`s flow better, but have big chambers and are light casted and prone to cracking. the 305 has small valves, small ports, small chambers, and are also light casted. so in your case, i`d get the 882`s milled maybe .010 and use GM head gasket 10105117 which has a compressed thickness of .028 the milling and thin head gasket will help compression. good luck.

I agree you will get better revs out of the 882's. 305s realy limit your top end.

You know, you could have just added this to your other thread....

I'd say hands down 882 over the 305's. Flow is much better, and you don't really want the compression that 60cc will give you what with gas $ the way it is IMO

And if it's a thin head gasket you're looking for, look at the Fel Pro 1094 with a thickness of .015" but also a smaller, 4.100" bore size than other gaskets
