Do you have a vacuum gauge? If yes put the gauge on it and report back. Did you assemble the engine? Especially the timing set and installing the distributor?

This problem has been consistent since the engine refresh?

How did the spark plugs look when you had them out for the comp check?

Is it possible the rockers are improperly adjusted without affecting the comp check?

Positive stop valve train......no lash to set.

It sounds like you’ve made some headway but did you measure for the correct length pushrods during engine assembly?

I don’t think cutting (someone correct me here if I’m wrong) .020 off the block decks is gonna cause you to hang a valve open with a stock length pushrod but if you’re timing adjustment don’t fix the issue you may want to look at pushrod length.

Put on you’re fancy lab coat and watch a few Bill Nye the science guy reruns while you wait 😂

Come on Dan, do the right thing and send us some virtual 🍺 🍺 🍺 😂

Glad you got it sorted out and didn’t throw any of those old distributors away, sometimes being a “collector” of spare parts pays off.
