Exhaust Valves

The stock valves are inconel - and are perfectly fine for pulling and high EGT's, I use the inconel valves supplied by SBI(made by Eaton). Having good strong diesel specific exhaust seats installed(durability), and a good wide seat width(contact patch between the seat and valve - wider transfers heat better) keeps things happy.
