360 magnum. 1 piston lower in cylinder??

A lot of GREAT info guys. I really appreciate it!! I put about 120 miles on for what may be the final cruising of the year. Getting cold here and I spend a lot of time in the woods this time of year. Anyway...had a blast hammering the heck out of the Satty.
Here is the plan for the coming months.
Install my SG and 3.55 gears.
Tear into my LA360 and have a good look around. If I find all is good then I really like ham's low dollar, high compression piston and EQ heads. Add cam (TBD) and Crosswinds intake all using AJ's calculations.
Not sure what to do with the Magnum except have a hard look for cracks in the head at #8 (head gasket was good) along with the cylinder walls.

Cheers
