I don't own a high speed tachometer although it would be nice to have .Old school ,just set them by ear .

The  times I've checked a few I was pleasantly surprised they were running several thousand RPMs above factory max .Once you  change the porting scheme the factory suggested max speed no longer applies .

You know you run them a bit and "read" the plug .If it's that nice light brown color you're pretty well on the money the way I see it .
