Ummm, on the, stroker engines page, the Canfield 195 exhaust ports flow up to 30ccfm. more than what my Canfields flowed a mere 3 weeks ago. Same head as they show. The intake #'s between .200 and .500 was also higher by around 10ccfm. And the site shows a 2.02 int. valve where mine came with a 2.055. I am looking to get that 30ccfm. on the exhaust from bowl and port work, now.:yes:

Mama always says, "don't believe nothin you hear and only half of what you see." I guess Mama is right again.
