Ive got a head im looking at rebuilding for my engine, it measure 72.6mm, should this be ok for 22psi on my t25 generally ?

thats a tuffy!! i'd say not ,u'd at least have to have an adjustable timing sensor if it pinks and it probably will!!:)

hmm thats what i was thinking, my head on my current engines 73.4 so ill probably stick with that, will just clean up the threads on this and stick it on a shelf as a spare.
