What is your quench?The int ports can show reversion or rich fuel wash I think.I would think a dome piston is better than milling the heads.jmo.
Use a dome if you want to make less power, otherwise do yourself a favour and have them angle milled. 0-.300" is possible with these castings. A dowel shift is a ton of work but pays pretty big dividends. I could go on and on. Depends on how serious you are of course just like anything else it comes down to $$$$$$$. J.Rob
