For the oil pan, don't use a gasket. Just use RTV Silicone. There is a little plate between engine and trans that needs removed, and then drop all the oil pan bolts. Clean it up, lay a nice bead of RTV around the pan and install.
For the compression issue, you need to get stainless steel exhaust valves and head bolts from
3Tech Performance and pick up a head gasket
kit with valve stem seals, timing belt, oil, and a filter. Then you need to visit either metroshultz or me or another mechanic nearby for a head rebuild. You may want to consider getting rings and doing the bottom end also.
Good luck!
