When taking my engine out I notice 2 adjacent plugs had very small gaps as if they had been hit, that was 3 years ago, now when I had the heads cleaned up and inspected, the machinist told me I had 2 slightly bent exhaust valves.. also adjacent, in both cases I dont know which ones, the gaskets i will use are felpros and they are .020 thicker than the steel gaskets that were on there.
My engine is a 283 from 1959 or 1960, the heads are from 58-61, part #3748770 and they say X-58 on 1 side, I believe these to be 58 power pack heads 64cc. The pistons in the engine say .040 on them and they are pop ups and the spark plugs were AC R44s...do I have the right plugs in the engine,if I do could i space them up a little, I also noticed small gouges on the outer portion of each of the piston tops as if something had been hitting at one time. Any guess what the compression ratio might be...and believe it or not, the engine ran good.
My plan is to clean it all up, timing chain, rear main seal, all new gaskets, paint and do up the whole engine bay,...put the motor back in for a few years and then do the whole drivetrain over to a streetrod.

I 'm not to worried about the valves, as i said, they were minimal and it could have been caused by valve timing or timing chain or detonation, this stuff will be corrected plus the increased thickness in the head gasket i will be using.
Somebody at another forum just informed me that the plugs that were in there were wrong...S means extended tip and that i will have to use the R-45's since R44 is no longer available... remember, i have pop up pistons!!!
