I think itís the nature of the beast with both those exhaust valves being so close.
Its why the Arrow (H&M) RAV with no pushrod will be where its at. I would like them not to only make the 8 deg giant raised port version but the lower profile 10 deg head too.
Dave can make them to fit a 4.155 bore, factory block deal. There is enough room to make the port any size and shape you want for whatever bore size you have,
They are the future of reliable, high end Pontiac racing IMO.
