Hey Everybody,
I have E-heads with swirl polished valve, solid roller springs and multi-angle seats.
What would be a good lapping compound - Brand, Grit, supplier for my application?
Engine book recommended 600 Grit.
Thanks Again, Craig

Re: Lapping Compound?
First question is why are you lapping the valves? Are you freshening the engine? The seats may be out of concentricity with the guide and shound be done on a seat maching if they have been run with that much spring. JMO
Clover brand has been the standard for overv 50years. Permatex also has a lapping compound.600 grit would be the absolute coarsest grit (a Finer grit would be better)if just checking the seat contact prior to back cutting a valve.
