the base cirlce radius is .732
base circle diameter is 1.463
and stock pushrods average out to be about 7.395,what i did was measure like 6 or 8 of them and average it together..
just for the hell of it my stock cam radius was .775 and the diameter was 1.550

most people will tell you to get the 7.4's because they are easy to get your hands on a set and most people dont know any better,you are running with to little preload right now,which is why it is ticking real bad.

Have you checked your lifter preload? .060-.070 would be ideal.
redtail2426 is correct in his recommendation of longer pushrods (7.425) which should give you .030 additional preload and hopefully calm/stop your noise issue.
