i have a gm head on my new engine and a coscast head on my current engine.
would it be worth swapping the heads over so that i have the coscast head for my new engine which will be running higher power?
what are the benefits of the coscast head over the std gm head apart from the porus issue that the gm heads suffer from?

yeah they can but very unlikely. The casting in the coscast heads is a lot thicker where they normally go porous, the alloy is also better quality
