Not A Taurus But A 460 Ford Big Block

I have a friend with a jet boat powered by a 460 ford I need to know about adjusting the valves and a couple of other things i've yet to find out apparently it's my new project to fix

Try a Ford engine overhaul manual from Haynes.They should list all of the tolerances.

if you could tell my friend the king of idiots isnt the best at listening to much thanks though
