Blew it up... GRRRRR!!!!!

This has to be the best reason I've heard so far. And I'll tell you why.....

Last night I replaced the two offending rockers and pushrods with another pair of used pieces so I could check the oil pressure. I removed the oil sending unit and screwed in a brand new Snap On oil presuure gauge I have. As I was torqueing down the rocker shafts I heard a distinct "snap" sound, as if a valve was sticking.... on both sides. Never noticed this when I assembled it the first time. Upon start-up the oil pressure was 50 lbs. at idle cold, 20 hot.... with no noises. I was also driving her hard this past weekend.

Me thinks I keep the revs down and plan on opening her up again.... Thanks for some solid advice Moper. As much as I don't want to do a valve job on new heads, I think this is the most viable explaination.

It never ends....
