marked exaust valves
Hi,
On my fi (18psi) cammed (#640 lift) ls1 with ported 241, i saw marked exaust valves (wear at the top of the locker place) last time (1 year ago) i pull the head
So, i swaped with good used valves
And now, just 7500 miles after, same problem...
I search and see it s quite a common problem (but dont see any pic) cause oem vavle have hardener tip weld...
So...
Common... normal... but without any risk ??????
Can i keep with stock eom marked valve ?
Should i buy manley hardener exaust stock size valve ?
Should i pay for a valve job to go from 1.55 to 1.6 inch if i need new valves (same price for the valve)
Should i pay for biggest (from 2 to 2.055) intake valve/valve job on the head since the limitation on 241 catedral ported head is the intake valve ?
Also, what does it cost the valve job for go from 1.55/2 to 1.6/2.055 ???
Best regard
