I Can't belive IT

[kaycee]

I took my 69 out for one last run before the cold hits and she let me down big time.I ran to town and as I got to the exit I noticed a valve tappet ticking no problem I'll just go to friends and re-adjust valves OK tick goes away.Go do some erands and head back home (30 miles)get about 10 miles from town and the ticking comes back and progressively gets worse then all power goes away,Pulled off side of road and thought I broke valve spring pulled the valve cover off and I noticed the valve like broke the bottom of the keeper off and bent the valve.Will take the head off this weekend and hopefully not see any harm on the piston side.Man this motor only has about 500 miles on it 327 with the 461 fuelie heads any one else had this problem?I can't figure out why this happened.Any advice or comments to help me out besides buying some new heads that I can't afford.That and thanks for letting me vent
