Well I was wondering where my head numbers stood for thoughs that had the big timers port and polish jobs.

Lift at the valve
Intake % /Exhaust %

.100\" / +27% I / +10% E
.200\" / +19% I / +10% E
.300\" / +14% I / +19% E
.400\" / +19% I / +23% E
.500\" / +20% I / +29% E

All ports were flowed on their own at 28inches, without intake or exhaust tubing.

How do these gains stack up to the big dogs gains?

 

it would be easier to decipher flow numbers for a pro in my opinion...I did notice it backs up a bit at 3 but otherwise looks good!

 

So are these numbers inline to what you would have done, except at .300?

 

We have never gone by percentages...

 

ok, yeah the guy that did my head was saying it was useless to compair flow bench numbers due to flow benches being different, but the gain in flow over the stock baseline flow of a head is where performance is realized. Unless you flow testing different heads on the same bench. Thanks for your input man.
