Yes the cam has the 106 lsa degreed in at 0. the headers are 1 3/4" I had a nother cam in this thing also 102 lsa. set 4 advanced and at 0. with .630 lift. I know if i did set it at 2 advanced it would not make that much up. I also have had the whole motor apart this summer and everything in a new fresh block. No change. I am about to sell it and go back to a stock head 454 and it will run faster. I would think this thing should run good with these heads. one of my buddies had the same heads on his 80 glass body race truck same motor ran high 9,s all motor and low 9,s with N20. Thanks for the help Bill C
