Bare heads, what valves

say i wanted to buy these heads bare http://www.store.procompelectronics....oduct_id=37061

what valves should i use there are so many different sizes.
i know diameter head is 2.02/1.6 and stem is 11/32" (there isnt an option for the decimal equivalent of that on summit), but what about overall length, and tip length

what would be a good valve for them.

Re: Bare heads, what valves

id stay away from those heads they can be hit and miss on the quality search the aftermarket product review for more info. But if you insist on getting them it should tell you if you need +.100 valve stems, otherwise you can get stock replacements 2.02/1.60 valves from summit the sealed power intakes are the cheapest and manely for the exhaust.
