my guess would be improper cam timing. the valves are probably open during compression strokes.

did you make sure to use a proper compression tester? those "hold in" ones arent worth a damn. a screw in type with o-ring gaskets works great and are only about 15-20 bux.

another option is improper tq specs on the head bolts, left a gap somewhere maybe?
