Were my heads angle milled?

Ok basicly I'm comming to the conclusion that my heads have been angle milled, they are AFR220's I baught them used off some guy & noticed no intake fits, when put on the engine the heads stick out past the center section where the intake would mate to the block leaving a gap.

The heads come from AFR as 76CC, these were heavily ported & unshrouded in the chambers which should hass another 3-4 cc, but these heads are now 58CC, now this leads me to belive there was a lot of milling alteast .140", the heads have a stamp that says:

020 110
58cc

to me this means they flat milled the heads .020 & then angle millled them .000 off the intake side & .110 off the exhaust totalling .130" of milling.

Does that make sense guys?

Because looking at the intake ports the floors have quite a bit of distance between the floor & the deck so meaning not much was milled there, buton the exhaust it could have been milled a lot.

Now, as I understand when angle milling, 1* = .110, so these are about 22* I would think now, problem is, I can't use a regular head gasket because of the milling.

I have heard of Cometic gaskets needed angle milling will this help the situation? & is using a head gasket that needs angle milling basicly put it back to the orginal angle? & if so is it better to just use a regular gasket & mill the intake side of the head to use an LT4 intake?

I'm confused guys, HELP!!!!!!!!

"when put on the engine the heads stick out past the center section where the intake would mate to the block leaving a gap."

If they are angle milled then the intake mounting face was not fixed for them. So you would have to have a intake manifold or the intake mounting face machined to correct the angle for them to meet.

Why can't you use a standard head gasket now? I'm confused about that.

bause of that, I heard commetic makes a gasket that needs angle milled heads so I thought it would just bring it back to normal.

found out they were from AFR
