Never say never i guess, but that's a big number for a 2.02 valve at only .550 lift from an OE head.
I would have tested another port if I saw numbers like that, as verification.
I ignore the .550 and .600 lift numbers. I'm within a few CFM on a 2.02 valve on a Flow Data bench. But I know, for a fact, he and I use a different valve job.
The rest of his numbers are close.
Just because you think it won't make it true. Horsepower is KING. To dispute this is stupid. C. Alston
