bench flow ze heads
Does anyone on here have bench flow numbers before and after port/polish heads. I was wondering what ballbark to expect after the headwork has been done. I know a lot depends on how extensive the headwork is but a ballpark would be good. Thanks.

Re: bench flow ze heads
Take this question to Probetalk. They have a lot more of this kind of information than we do here. IIRC from my reading there, it has been checked and the improvement was minimal.

Never attribute to malice that which can be adequately explained by stupidity.

Re: bench flow ze heads
I don't have solid flow figures simply because my bench is not calibrated and also
mine does not measure CFM but rather % differance ( google david vizard )
http://www.gofastnews.com/board/technic ... bench.html
in stock form the KLDE head flows a average of 230 cfm @ .300 lift
at what "HG" this was measured at I have no idea 28"?
The biggest gain was de shrouding the valves, and knife edging the divider
the ZE ports to valve ratio are already to big! so hogging out the port is
a waste of time..
