Inliners International Forums General Discussion Engines GM 4 cylinders 151 153 181

I pulled the head on the 153 today. It's .040 over. Quite a bit of soft carbon but there are still hone marks in the cylinders and no ridge. The piston is about .050. below the deck. The valves look good except for one intake that doesn't look like it is centered in the seat, but they are going anyway. It's looking like I'll only have to change the things I want to. The 181 crank is on the way.
