sounds good there with the jets , is the pv matched to your manifold vacuum?

get a pv thats rated 2'' of vac lower than the reading you get.

this is interesting! can u explain more on why??

This is right from Holley:

To properly size a power valve, take a vaccum reading at idle and if it is above 12" for a standard transmission a 6.5" will be safe to use. For automatic transmissions take a vaccume reading in gear at idle and if the vaccum is below 12" divide that in half for proper size. Example 9" of vaccume in gear at idle will require a 4.5" power valve.
