iron-mike Posted February 2, 2015 Report Share Posted February 2, 2015 Can a A12 head be ported to the size of an A14 head Quote Link to comment
Morrisun Posted February 3, 2015 Report Share Posted February 3, 2015 A12's had small round port intakes like the later A14/15 used in the Datsun 210. The B210 came with H72 oval port head. There was a 1200GX head that had larger oval intake ports but are getting harder to find, especially unmolested. It would bolt on and would have very good air flow, If you attempted to port and A12 round port to an oval like the H72 head- you would water passages- not recommended. Quote Link to comment
