This is a pair of 427 MR heads I had done about 20 years ago but the engine sat a long time and when I resurrected it I went with some TFS heads . They been completely gone through and have very low miles since rebuild...maybe 500 miles. They cc'ed at 86cc and have a good thumb print on the deck surface. On one each combustion chamber there are signs minor previous engine damage, just some minor dings that have been smoothed out and one exhaust flange has been repaired at some point.
Features:
All new Ferrea valves 2.25" int & 1.75" exh that have been reduced to 2.20"int & 1.68" exh
Crane springs and retainers 120# seat pressure
Hardened exhaust seats installed
.060" oil restrictors have been installed in the rocker shaft oil feed galleys.
New positive valve stem seals
All machine work done by Gessford Machine
I am asking $1800 for them + shipping or offer. If interested you can PM me
