Guess this could go in stock or mod depends how you look at it. Anyway being real short on used valves and not trusting the aftermarket pieces am thinking to contact Manley or some such valve maker and seeing about having a run of valves done in stainless. My thought is to have them done to carry the stock keepers and retainer but with an 8 mm stem in the guide area and under cut behind the head. Then also make them a bit bigger head depending on what I figure the stock seats will cut to. My thought are with the 8mm stem we can ream the stock guide to run the 8mm stem and avoid guide replacment or and this is what we should really do is find an 8 mm bronze guide. Every head I take apart has worn guides even ones I have replaced the giudes in, not sure this is due to valve stem wear or poor made guides. Just opened up a true 14k original mile head and guess what, the guides are shot so maybe it is just crap guides. Not sure what teh cost on these valves would be but am about to find out. Thought about teh datsun valve but some folks do not want to go as deep in the pockets as that requires and it would just be nice to have a real quality valve that pretty much fits a stock head.
