We've seen several here. All of them (so far) have been excellent. One even had my 12th birthday as a casting date!
We'll be looking close at Goatman's. It will be the first one we've seen not purchased through a Pontiac outlet (Ames and PY). Hopefully, it's the same as the others.
The aluminum version won't make more power "as is". It will, however, like aluminum heads, get you much more for your "porting dollar", as aluminum is much easier to cut than iron...(:-
