Question about heads.

[jdbubb at verizon.net (Dan Bubb)]

IIRC the front oil drain hole is larger on the JH heads than on the earlier 
head and the JH head has an additional oil drain hole on the front of the 
head between cylinders 1 & 2.. So, you'd need to get both of those welded 
up, redrill the center hole to match the earlier head and probably get the 
head surfaced. Other than that it's a straight bolt on and it has 40mm 
intake valves instead of 34 (IIRC) and also larger exhausts. The JH is 
definitely a better head.
