I've been doing research on cylinder head tech lately, and most of the info I find is either spotty or conflicting, ha ha. Any solid tech resources available for my reading pleasure?
The specific question I have at the moment involves which blank canvas to start with. I've read that the R34 NUR heads had some differences in water jackets for better cooling and air flow is a bit improved, but I can't find any definitive proof of that, or even an OEM part number other than the standard (11040-05U00). I've been thinking of ordering a new cylinder head to mate with my new N1 block (Planning on doing a Nitto 2.8 build), but I wanted to make sure I start out with the best OE head option possible (that's still available) before sending it off for machine work. Is there a different head available that's better? Or is it just internet lore and every RB26 has the same standard base cylinder head?
