Aftermarket/Replacement Cylinder Head Rule Change

Bob Mulry · 12-22-2017, 11:59 AM

I think that we are missing the point on these replacement heads...

Runner volume is just one way to compare castings...

With the new replacement castings I would like to know what the flow numbers are from each head..

Just because the volumes are the same it has nothing to do with air flow or the horsepower that they are capable of making..

It looks like another can of worms just got opened for Stock...

Just sayin'
