I'm taking a class in High Performance Engine Machining at Sinclair Comm. College in Dayton, OH. I had a set of 576 casting small block heads that I just did a valve job on, and then put them on the flow bench, just to see what they would flow stock. They were 206 on the intake, and 166 on the exhaust side, both at .600 lift. Is that within a good range? So I just wondered if anybody else has flowed some small block heads, and what they came up with. I know they talk about the X heads are supposed to be good, and the 308's, but does anybody have any numbers? Just curious.
Thanks,
Dan
