Nice job with the porting. I note that in all the videos I have watched, the presenter has not physically bolted up the exhaust flanges to the relevant ports using Prussian Blue or Bearing Blue, then unbolt to confirm the areas to be removed for a near perfect match. Maybe your gasket match was good enough. Well done anyway. Cheers
Good job ,wish you would have shown your finished head next the stock head. That way we could know where the starting point is and where we are working towards . But i learned alot thanks . What part of Tennessee are you in .am in Murfreesboro
What model Mawalkie die grinder is that your using? I like the idea of using battery power instead of air too. Your link doesn't work from my location.
