N42, bigger valves (than early e88) , hardened valve seats, have the perfect chamber shape for hp, just need to shave he pants off it if using dished pistons, or 1-1.5mm if using flat tops, oh and try som someder singh gooves (google it) to increase compression turbulance.

 

ready for ULP (lead free petrol of any sort)

newer, ie less overall wear/use (hopefully).

better materials being newer.

plentifull supply as the 280zx had em.

 

 

should i keep going???

PS if using carbies, plug up the injector notch to reduce intake charge turbulating prior to getting past the valve seat, by either welding or epoxy resin.

I know I'm getting excellent results with a N42 head. I managed 150+Kw at the wheels with one. Had a P90 for a while sitting around so I hocked it off on ebay. I guess any cylinder head you throw money at should flow..The triple combo should get some more hp as well.
