I dunno how you would tell, without a p/n on the head,Maybe If you measure the squish with silver solder after the engine is assembled someone on here like glenine might be able to help you with the compression ratio, and I'm not a big fan of shell gasoline I don't like there additives it turns clear gas tanks yellow, stick with esso or petro-canada, but this is my personal preference.so how do i tell which domes are in it? compression test when i get it back together? the shell V power not premium? or if it is couldn't i just add octane boost?
I have no experience with octane boost, so I cantt help you there. sorry
