the jets sound good but the power valve? check the power valve make sure you did not blow it out. with that cam you should valve good vacuum and may not need a 6.5 a stock 8.5 would work? maybe .you will not see much from the two ? how much vaccum do you have in gear at a idle and go from there i allways split the vacuum and that would be the power valve i would use so 12 would be 6 power valve and tune up or down from there . i am thinking the back is pluged? that is why the 80 jets in back?
