I test at 38, 32, 38, 42 regularly. I now have the ability to test at 60" inches plus some.


So what you really want is for those of you didn't pay for something be given that for free, just because of the internet?

I will say this...if your cylinder head porter does not test at a MINIMUM of 28" all the time, and is not using higher test pressures on a regular basis (especially with the intake system installed on the head) you are just pissing performance away.

It's that simple.

Comp, Pro Stock, Azzcar (and I know for a FACT Stock and SS guys) are testing at pressures up to 100"!!!!!!!!!!!!!!!!!! They ain't doing it to post big numbers and run their mouths on MoParts. They are doing it for RESULTS.

Take that to the bank.
