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!

 

I would call Canfield and see what they say.

When you install them, make sure and check your rocker the way it sits on the valve just to be sure though.

Thanks Lloyd. I just found their site and phone number.

 

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.
