Loffy770 Posted August 2, 2018 Report Share Posted August 2, 2018 So in my rebuild I will use new valves and I need some advices before I start. I seen that some like VPW sells new made vales and guides for lead free fuel use.. Is lead free fuel a problem or can I use original NOS valves and seats? If I get new made stuff, where do I buy quality valves and seats? And what about springs, will old stock do it or should it be new made with higher spring strength?

Plymouthy Adams Posted August 2, 2018 Report Share Posted August 2, 2018 original seats are hardened and as what you need for lead free fuel.....VPW is one source.....there are others..shop about......as for spring rate....at the low RPM these engine operate the spring rate as is stock is more than sufficient to close the valve at speed.....inserting higher rate spring with stock cam will more than not cause undue wear and tear on tappet faces and cam lobes...

tom'sB2B Posted August 3, 2018 Report Share Posted August 3, 2018 I would recommend Terrill Machine from Texas. He will sell you guides, valves, tappets and springs and ship them the next day. Very knowledgeable, no BS. Cheaper then VPW Other options are : Egge Machine or. Kantor Machine I find VPW to be the highest priced parts supplier over all. Good luck!

Loffy770 Posted August 3, 2018 Author Report Share Posted August 3, 2018 Thank you guys for the answers. As for valves I will need new ones, I might find and valves and springs locally from old army surplus. the original tapets look very good with almost no wear. Neck is 0.01 less than my NOS set.
