is the p90 head valves the same as the p79?

also what are the stock valve head diameter? stem diameter?
I am looking for direct drop in stainless valves slighty bigger head (of course that has to be machined) for a p90 head

Thanks

no one has built a head with stainless valves? lol

Go to page 63 of your 280zx Haynes Manual. It has the specs.

Also... are you going to install the valves yourself, or have a machine shop do it?
