Hi,
there is nothing wrong with a A-series that a turbo can't fix.

nothing strange to see between the valve seats, and were the valves sit.

The coloured spot looks like a valve guide tightened and caused a huge amount of heet to be transmitied into the guide hole caused friction between the guide and the valve, I have seen this on many race motors most times I have had to press the valve out of the guide with a hydraluic press.

if a tightened valve guide was the problem. I would suspect the heat spot more to one side and not so in the middle or is this wrong thinking there is nothing wrong with a A-series that a turbo can't fix.

Ok on closer inspection of your pic it looks like EGT was what caused the problam If you look at the pic the blueing is only around the exhaust valve and ports I would hazard a gues the Ignition timing was your problam or elve the rong type of Exhaust Valve guides if it was on a turbo.

But EGT???????? i did have problems to get the ignition right off the engine it came off
