stock head and GM tranny question in one

[VooDoo]

Ok first off what are the hp limits of a stock head? Who has made what power? It has been rebuilt but with stock size valves. Only exception is the machine work for mhg and coated exhaust valves. Otherwise stock.

Secondly. I am seriously looking towards a th350. I have found I can't use an AEM standalone ECU, on a stock a340e. What about the th350? Is it just the electronics on the stock auto?

1) Sean X-Man dinoyed 753RWHP with stock head using GT42 turbo
2) TH350 has zero electronics in it. If you want to stay A340, you can use aftermarket tranny computer (suprastick e.g.)

753 wow that's some impressive #'s on a stock head. Hopefully coating the exhaust valves will not be a waste of money. Or even hope it will not affect performance. I wouldn't think so.
