LT1 Canfield heads - Which Guide plates?

I'm getting a pair of Canfield heads but my current rocker arms are the Non-Self aligning CompCam 7/16" 1.6 Promags. I know these are considered an 'extinct' type of heads but does anyone have or remember what guideplates these heads would use? Since it has large valves, I'm sure the rockers are offset from the stock LT1 settings and thus cannot use my current GM guideplates.
Thanks!

Well, my Dart 230 cc heads used regular guide plates, but there are adjustable pieces also, if i find the PN i will let you know.

It's appreciated. These Canfields sport 2.05/1.60 valve sizes so I'm almost sure the intake valve is offset a bit from the stock location.

Isky adjustable guideplates will work.

Just got off the phone with John at Canfield Heads. Super nice guy. I ordered the guideplates from him. He told me some pertinent things to look out for on the head gaskets too.
