40--41 A heads

[Walt Dupont--Me.]

Mike, your right, I forgot they went to the electric temp in 40. I know those 6049--6050 are usually cast in on the top inside of the head. but this one heads I have I've wire brushed all over, the only no. are a couple of single no. on the face. I'll glass bead it, I'll probably never use, but some thing like that just bothers me that I cain't figure out what year is ect. Thanks Mike. Walt

Mike, Will the 81a heads work on either side? My are installed with the numbers in front. Piston #3 and #4 are hitting the head. Thanks,

They will fit and function on both sides. However, the water ports are in fact different, right vs. left.
There is no difference in the combustion chambers so the pistons hitting is indicative of a different issue.
On the concourse, heads on the incorrect side should be noted and a deduction given for same.
