Trying to get advice on my first jet boat engine build.

-1978 F&K Marine 18ft boat (can't find any info about this boat)
-Berkeley split bowl (not sure what letter impeller)
-through transom log style headers

Bought boat with a seized engine and what I found on the tear down is motor has dove heads with stud mount rockers, stealth intake, Holley 750, unknown cam, scorpion roller rockers, truck rods, stock .030 pistons. Looks like the crank spun 1 main bearing so I figured get the crank turned and re-ring/bearing with flattop pistons. Any suggestions for a good warmed over stockfish build??
