GM heads dont go porous as such, the casting cracks.
Coscast heads are just less prone to that. And thats there only benefit, they wont give extra power like a shit load of people seem to say,lol.

Your shell doesn't really need it mate. The post 97 shells were strong enough to take a XE as standard. I've done 10k on my conversion and it can take it fine.

Not sure how much we would charge. It's split work, and i'd hav to check on the engine. Labour is typically about £600 for a conversion I think.

isn't the vauxhall head actually better because it's got bigger intake ports or better intake shaped ports?
