The Ford Barn - View Single Post - 8BA head mismatch-I should probably fix

On my 8BA in an 8N tractor I have an 8BA head on the right and an EAB head on the left. The machine shop that I used gave me the EAB head because the LH 8BA had a crack. It's been running fine for almost 10 years now, but from what I am reading, I think I should probably find a match. Seems like the EAB is a more desirable head. Not seeing any RH EABs on Evilbay right now but I do see some (pairs) of EAC Mercury heads. Of course, these are heavy and shipping is expensive.

So some questions: 1-is this even worth worrying about? 2-Is EAC equivalent to EAB? 3-I assume cracks are a real concern on used heads or not usually?

When I built it, I used a stud kit for aluminum heads but I just can't see paying up for those. I don't need more power, it's scary enough as it is. Thanks for your advice.
