I just took it to a machine shop and let them rebuild it. Heads were cracked, they provided rebuilt 906s. Single roller timing chain, marine cam, Holley timing cover, ARP rod bolts. Machine shop, did the typical machine work, bored .020 over, decked, polished the crank and balanced the rotating assembly, resized the rods, stock replacement but coated skirt pistons, brass freeze plugs. $2200 otd.What did you end up doing?
