Re: Ticking/tapping noise, 305 Chevy, Can't Figure it Out!

Run a straight edge over all the rocker studs to see if you have one pulling out.
One sitting higher could change the rocker contact on the valve tip.

And check the valve tips for strange wear patterns.
When you check the pushrods check for any rubbing marks.
