Valve stem seals
 

Hey folks, I’m doing a job on my 92 silverado 350 engine replacing the valve stem seals. Mine are all but gone. Traded for this truck last year and i new it smoked as they sometimes do. So my question is what do you guys recommend i buy for exhaust seals. There seems to be several available. I suppose the umbrella type is what i need but there are many brands and materials. I’ve already bought intake fel-pro seals. Any input will be appreciated.
