I have an A15 rebuilt as is the case with my dad. There is nothing wrong with the A15 head as it does have a good closed combustion chamber. Most of your porting should be done with the exhaust because these engines need to breathe and breathe good. My engine has datsun 1600 exhaust valves but it is recommended that you take a nick out of the block and maybe even the piston (depending on the lift) to allow the valve to move without danger. hope it has helped.
