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.

oh thanks for your input!
it try to get in touch with Harlandsharp about this problem.
At the moment we have HA5003, HA5016 and HA50026A as "maybe" possible solutions on the table, if i stay with Harlandsharp Rockers.
Great!

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
