valve stem seals- does it matter?
didn't realize there were so many differnent types. i all my 4wheelers, dirt bikes, and crotch rockets- i always used viton- because that was more or less what the shops always had in stock.
viton, teflon, o-ring, umbrella, positive stop, etc............is one any better than another? 6500rpms max street/strip
crane makes some positive stop teflon seals- reasonably priced. will those work? i believe the dart pro1's have a .500 guide and sbc valves are 11/32 if i recall correctly.

sorry- the O.D. of the guide is .500 and the diameter of the valve stem is 11/32. i was just stating those two dimensions- to make sure i was looking up the correct application on summit's site. didn't know if there was any advantage or disadvantage of all the different types of seals.

I vote for OEM style if available. Knowing the OEM's work so hard on emissions, mileage, cat life, etc...
I think I bought a set of OEM style from Fel Pro last time. No oil burning at 7000 rpm yet after ~15,000 miles.
