110 head mod

Why not get a plug for the ACRs instead of welding and heating up the heads and perhaps loosening up a vlave seat or guide? IMHO, it would be better to look at a dome piston to get the compression right; if that is your goal.
From what I understand, those heads can be made to work well but if they are among the poor quality batch, new guides are in order.

Even if you plug the ACR. you can't bring the cc down enough to work with a flat top and get decent comp. There is a few issues that a local indy could fix at not much of a cost. these heads need they're guides replaced with some quality bronze guides and a new valve job, some new springs and they're good to go.
You can pick up a SE 103 10.5:1 piston for about 250.00 made for these heads.

6cc puts you at your target, and is easily obtainable.
You need to pull those down about .075", before the realeases are in the way, and even then, you can back those off via a crush washer, or copper washer.
