Contact Tim and he'll steer you in the right direction.

I wasnt really trying to run down anyones head, just trying to make a point. These heads are a great casting, much better than the older MP problems with common quality control trouble.

I also know that these were flowed on the same bench and probably same operator also. So IMO they are a decent comparo.
Looks like they are a hair better than the Stage V's, probably NOT worth a small measurable amount of power...maybe..

These also have stock valve sizes. port locations, valve angles etc.
