is not there a cam from later tractor to put in older tractor that may help boot the power like putting a cam out of a jd 60 in jd A?

I was told that 620 and 630 are too far different. and 60 will work. I not really so sure what my choose will be.

I have it in writing from the Two Cylinder Club's copy of JD specs, JD parts manuals and from J.R. Hobbs copy of JD specs that the late A, 60 and 620/630 use the same lift and duration. Intake 10 aTDC/40 aBDC and exhaust 45 bBDC/5a TDC.Valve lift is .4536" All the 60's had larger valves than the gas or LP 620/630 as well.
