850 R Compression Cylinders 2 and 3

Just bought an incredible '97 850R with under 100K miles. The car has been sitting a long time...the guy I bought it from bought it with a bad miss from the original owner. The rear cam seal was leaking BADLY and the dist cap was completely corroded inside... I put a new seal and new cap/rotor/wires on. Car still ran terrible. Did a compression check as I know there is a lot of gas in the oil. Cylinders 1,4 and 5 have 160+ and cylinders 2 and 3 have 0...not even a HINT. My mechanic in Dallas (5 hours away of course) says do a combination of trans fluid, Marvel Mystery and a touch of good motor oil...about 1/8 cup in each cylinder and let it sit three or four days, then do a good oil change. I've been around cars with bad head gaskets, and they at least had SOME kind of compression register.
Any advise? I really don't want to put a used engine in it but will as I got it for a steal...the interior is near flawless, the exterior is nice, and I have a great set of chrome directional 960 16inch wheels to go on it. It is white with a black interior.
Thanks ahead of time!!!
