Hello all, I just bought a 1963 Ford 4000 all purpose, 4 speed, 4 cyl. I knew the engine needed rebuilt before I purchased it, and I want to do a one and done on it. I pulled the engine last night and plan on replacing all seals, bearings, pistons, etc. I'm wondering if it is worth the trouble to have hardened valve seats installed? The block is not sleeved, so I'll measure the bores when I get home and see if I can get by with honing them. I pulled the rod bearings to see if there was an oversize marking on them but the only thing I could see was the factory part number and 500 stamped in them. Any help would be appreciated. I am a heavy equipment mechanic by trade, so hopefully not too much will be beyond my skill set. Thank you!
