oops! now how does this happen on the exhaust side?

Rocker clearance or piston to valve.

Not sure, but you better find out quick!! I had a small bock that had some "s" shaped pushrods, over RPM with a solid cam was the issue at that time. is this one or all exhaust valves??

check the valves and see if they are bent using a leakdown tester and check ur valve lash, loose, or even piston to valves hitting or collasped lifter if ts hydraulic, did u over rev the motor into valve float mode??

Here's the tricky part guys 5 out of 8 were. Bent on the passenger side and none on the driver! How in the world does that happen? Now take. Note this was the worse one. All the others wernt that bad but still a bend is a bend. The clearance is good especially since the pistons have valve refiefs in them.

Rocker clearance? Help me understand that? Please

 

[kidmopar]

go to comp cams website it will tell you about rocker to retainer clearance at the rocker tip. i had some that were corrected with lash caps. if the rocker hits the retainer it can cause problems for ya

So can coil bind. What is your combination and what engine are these on? A big block?

LOL OMG i think i should be shot right now after finding out what i just found wrong! Tell me just looking at this crank gear which 0 would line up for the timing mark to match the cam gear??

 

[Homstead]

The 0 at the tooth, not the 0 at the keyway.

 

[Gary_gtx67]

[Homstead]

Lols,, Stuff happens sometimes! If we didn`t make mistakes we wouldn`t learn anything. Don`t be to hard on yourself!

 

[Gary_gtx67]

Just fired it up again and running the carb and already wow!!
