AQ125B head on a AQ120 block, any problem?

[pugetsounder]

As the subject says any problems putting a B230 head on a B21 block? Will it fit? Will there be any interference issues? Most parts seem to be the same.

According to this, they are exchangeable.

I haven't tried, though.

Wow thanks for the quick response El-pesc. The head is in the machine shop right now and they were ready to start working on it. I just noticed last night the valve cover from the head said AQ125B and it dawned on me this is not the B21 engine. There are different numbers for headgaskets and head bolts. I will use the gasket for the B21 block and the bolts for the B230 head. The good thing is the head looks like brand new inside and out so I'm happy I get to use it instead of patching the original with the corroded exhaust port.
