i think the cosworth one doesnt go porouse (sp) and the gm one does but then again i might be wrong

According to a local engine builder, you can flow, and port them the same.

He races a mk2 cav, with some stupid power xe in, and he is on a gm head.

exactly, i know of 2 xe'as with gm heads and 150k+ on the clocks with no issues. its the same design, just made/cast slightly differently.

now the sleeve fix is well known i would go for a gm head every time as they have considerably bigger ports as standard

But the costcast ones have more "dead" metal to port into:confused:

Can't see ebay at work, but what car do you get with it for that price? lol

BTW the no ebay links rule applies to item numbers as well :roll: I've left this one as its not the kinda thing anyone is likely to bid on. Unless they're a turkey.
