I agree on the rocker-tap thing,but adjusting the valves/possible head-work may be in the works,if the Kroil doesn't work. It still may be a good idea to install hardened valves and guides in your head,to accomodate the un-leaded gas,since,more than likely,your 292 was designed to run on leaded fuel. I had an engine that sat for 6-months,that was stuck so bad that I ended up junking it. Of course,it wasn't a "Stovebolt",with readily-available parts,either. I used EVERYTHING but Kroil,and it soaked for 5-years! The # 5 cylinder still had about 1-1/2" of tranny fluid,Marvel,P.B. Blaster,brake fluid,and WD-40 sitting on top of the piston. The exhaust manifold had a crack in it,and condensation got in through the valve.(open 100%),when shut-off,right at the crack). I've heard several people swear by Kroil. I wish I would've heard of it before I scrapped that "Stude" engine. I tried rocking it from time to time too. The truck was cab and chassis,so I dis-connected the drive-shaft,put the transmission in 4th,and put the end of a long pry-bar between the front U-joint.I added a 3'long pipe to that for leverage. The clutch slipped, but that engine wouldn't budge! Hope this helps.
