update...

well, after i got past the momentary brain lapse that was the switched plug wires, and have since solved the cooling issues which probably caused the overheating and cracked head in the first place, i'm still plagued by yet another problem and i can't seem to get past it....

the Trooper starts, runs and idles just fine, cold. however, once things warm up a bit, there is a periodic 'squeel' or 'squeek' that comes from the valve train (or at least i think), though idle remains normal. the squeeks will increase a bit with RPM, but aren't constant. the sound isn't like valve tap to me (of course, my only experience being Chevy 350s), but for some reason, i do think its coming from the valvetrain.

Now, i've always had this since first firing with the new head and cam. I've have adjusted valves (set at 8/10) and checked til my knuckles are bloody. i have also gone back and 'clearanced' the little rocker shims/retainers for the extra lift of the delta cam so they are clear from the path of the rockers (i read about this issue w/ Delta cam installs).... noise is still there.

any ideas? doesn't sound like the valves are out of adjustment, but maybe i'm wrong?
