Thanks for the replys. I'm currently running Harland Sharp 1.5 with the Edelbrocks and no issues. I thought trying a set of 1.6's like the ones for sale by a member here would be a good way to see if the car would like more lift. Since the heads have not been ported I have my doubts. My pushrods are 5/16 Comp Cams.

Thanks
GM
