Quote: WOW you have to degree a cam now days with production tolerances dot to dot can be out as much as 20 degree 2 or 3 make a big difference on a tight 108 LSA cam
To check your harmonic O/TDC line with heads on you need to buy or make a piston stop. On compression stroke or better valve train off driver side turn up from BDC till piston stops agains stop mark balancer then reverse back to stop and mark balancer again 1/2 way between the two marks is true 0 TDC. you can buy one of these http://www.summitracing.com/parts/CRN-99412-1/
or make one out of a gutted spark plug taping it out with 3/8 threaded rod or a bolt with threads cut to head.
