You would think jetting up is easier than swapping heads just to see if the engine builder has a clue??




Somewhere along the line in these many threads the carb change has been suggested , a few times , but the OP is STUCK ON FACTORY STOCK and poo poo'd a carb change , or the carb , being the problem.






I'm pretty sure carburetors are more mysterious today than fuel injection was us 30 years ago.




I remember opening the hood on my friends 63 fuelie vette in the day.. Pure magic....

Anouther idea with the hot head, is it getting enough oil up top to cool the springs and head, any restrictors? Pull valve cover and look for oil splash. Part of oils job is cooling and shaft could be in backward or stopped up.
If oil is restricked one other culprit is the cam bearing holes not lined up.
