Ok so I'm under 1.5 from center of the roller to the fulcrum area. Like 1.4 best I could measure with the rocker arm on the car and I did it a few ways. Dial caliper and a dress makers measuring tape lol. Of course the measuring tape wouldn't be exact but it backed up my dial caliper measurements. A few pics that may help.
so i have 1.511 Inches (38.38mm) and you are at 1.4 inches (35.56mm) with these Ford 302 (1.6 Ratio) Rockers.
This is a difference of 2.82 mm / 0.1110236 inches!
uff.. i think these Ford Rockers would fit closer to the center of my valve tips.. whats your opinion?

I had a similar issue and ended up going with the harland sharp S50026A set up, there is no machine work needed and my factory length pushrods were the correct length. I found it to be the easiest solution.

the S50026A work with no machine work needed and i believe are rated for at least .500 lift, i have a little more lift than that with my cam and I have had no issues. good luck
