Do a compression check on all cylinders. Compression should be at least 120psi.
If compression is low, recheck timing (although you've did it a couple of times already).
Next, perform a cylinder leakage test on the engine (if compression is low) B sure to have the cooling system full while doing this test (if air is escaping through the water jackets it shows up as air bubbles in the cooling system (if you don't have water in the cooling system you can't see the bubbles).
