I was just looking inside the exhaust chambers for my 1964 110 hp head and it looks like a kink in the exhaust side! Has anyone ever milled that groove off down near to the guides because I don't know how the exhaust can get through there? It's like a 90 degree turn.

Re: Exhaust Valve Questions
Typically I will use use cutters on a die grinder and do a bowl blend as well as taper the area around the guide down. The flow picks up significantly when you do that.

Re: Exhaust Valve Questions
Have you ever ground it down all the way to just enough material for the guide?
