Allright. It's apparantly unanimous (I hope I spelled that right). I will be installing 95 HP heads in my Rampside PG. But which ones? I have the 1965 with fresh valve job bought from Dave's Corvair Shop in Albuquerque or I can use my 1969 95 HP heads (flat combustion chamber- unlike the 1965 which has a raised step)also with a fresh valve job.So again I ask, which set?
