I need some help with which valve stem seals to go with i have the crane 10308 spring kit and the heads are stock and on the motor . Which valve stem seals are good ones to go with and does anyone have a part #s. thank you

 

comp 503-16s and i have the same spring kit

by the way, what cam are you running?

 

i just run fel-pro oem replacements have always worked good for me

 

gm 847 cam with 1.6 rockers

 

what are the specs? i'm cam shopping now and looking at the cc305 but not positive yet...

 

But the car in your sig is a V6? On any note the 847 is MASSIVE compared to the 305.

 

what he said. My 847 is WAY larger than any cam I'd stick in a 350 without serious head work and the will to shift at 7000.

 

Why does Summit say that machine work is required?

Anyone else have an opinion on the felpro seals? Will they work with the Crane dual valve spring kit?

Thanks for the help.

 

I prefer to use factory or OEM replacement seals if it will see street duty. I know the factory seals will work just fine with those springs.

 

Thanks. Is there a reason for your preference?

 

Simply, because they will last. Teflon or any other "trick" seals that may be available were never designed for daily driving.

 

I used a set of Victor Reinz (Dana) valves stem seals and they looked well made and have performed well.
