Finally getting around to another project engine I bought several years ago from a supposed reputable builder that has name recognition and a huge business dealing with FE's. I bought a numbers matching '69 428 CJ that was bored +.015", and supposed to be ready to dyno test. Since I had some time on my hands, I decided to break down the heads and check to see if there was any work done in the bowl area, and guides, etc., thinking that I may go ahead and port the heads and intake manifold for this project vehicle. What I found are three cracks in the intake valve seats in one head, no valve job on some of the exhaust seats, and no guide work, umbrella seals, and one port was so rotten from water damage that I am afraid the rust has eaten all the way through to the water passages. This engine was supposedly ready to put oil in, and start up. My question is can the intake seats be salvaged where the cracks are located, or will I need to have intake seats installed? The exhaust seats are hardened, but no valve job. I am reluctant to install both intake and exhaust valve seats in the same head with all the seats replaced. Has anyone had good results with fixing this kind of a problem, and if so, what was the fix? Joe-JDC
