Thank you for the info. I was most concerned putting rectangular intake manifold port on the oval heads. Am told using both types of gaskets (lining up oval and rectangular gaskets with appropriate sealant will allow this misfit to occur without leaks or loss of significant air flow thus power. Will plan to use Aeromotive phantom in tank fuel pump with post pump filter. Borla has an inclusive system with exception of pressure gauge and need to plug an O2 sensor in the exhaust header. Also expect the need to change out distributor (large headed mechanical) although if space allows could lock it and still use it.
Have heard the same pluses about the Holley HP. Will decide between that and the EZFast 2.0. The latter doesn't need a laptop
This is my winter project and look forward to anyone's input and experience to ease my pain
