I am impressed. I blew a head gasket (Mr. Gasket) after 29 races and 3 years in my vintage car. It blew between 5-6.
After pulling the engine and inspecting everything I found the main and cam bearings were in excellent condition. Timing chain was perfect. All of the wear was in the value train and heads. It will need a valve job, and I'll stick in new springs (they tested within spec). Since the engine is out, I'll replace all the bearings and chain. No cam wear. No cylinder wear.
302 w/ iron (race rules) 351 heads, 6800 shift light, Mobil 1 15W50. Next time I'll pull the heads after 15 races and freshen it (including head gaskets).
Pushrods are not obsolete.............
