Hi Guys,
I’m looking at getting hardened seats in my head and I just want to know whether I can retain the original valve sizes?
I’ve never seen an unleaded head but from a quick google search it looks like they have the same size valves?
Cheers
Tim
That really depends on the size of the valve and the seat used… ie if you have larger exhaust valves then possibly not as the material removed will weaken the insert allowing it to become loose standard valves are not usually an issue
