Early engines are round tooth on the timing belt, later are square, both have different head bolts

same with late ones. Coscast head is massively over rated.

The castings meant to be better, early ones had bigger valve guides, coscasts are less prone to going porous.

Yeah possibly, they are over rated, for a fraction of the cost of a coscast head you could do the porous mod to a GM head which imo would make it just as good.

cos cast is just as likely to go porous. Far better to buy a gm head for 30 than coscast for a few hundred.

best thing about them is they have harder valve seats. But thats only really of benefit to some one fitting over size valves. The later gm head is actually cast better in the ports etc.

i see well you learn something new every day. so really unless your fitting oversized valves the gm head is your best bet?

yeah i know what you mean was just if you didnt have either and you were buying one as the gm one will be a fraction of the price
