Changing back to the M20 motor in my E30 ChumpCar for this year, so have a few M50 related parts available.
These were used in a race engine for 1 race in 2013, approximately 10 hours run time - cyl head replaced after ~5 hours due to a miss-shift that bent a few valves, engine disassembled after next ~5 hours.
ARP Head studs, washers and nuts (ARP #2014302): have been torqued twice, still measure same as new - basically good as new. $150
Cometic MLS headgasket - debatable whether this are reusable, but if its going into a street engine it should be fine. A few cyl have some sign of valve contact, but it had no issue with sealing. Was re-installed after first 5 hours, no leaks or issues for next 5 hours of run time. - $50
Would be willing to do a package deal both items - $180 obo
$10 shipping.
