Good point on the valves. I would definitely have to check those. Bore notches wouldn't be that big of a deal if that is all it takes. Cause I want to do a minimum over bore to keep the walls as thick as possible.

If the valves aren't an issue would the Eddy heads or Stealth heads be just fine or would I need the extra flow of the Trick Flow heads?
