Thanks for those measurements,, thats exactly what i needed,, guess the 2 hole(notch) gasket was the right deal,, but the #4 piston is definately bent and I'm thinking the #1 might have got a hit 2 judging by the numbers.
And yes I measured em all at dead center of the piston,, just wish I new all this info about these engines the last time I rebuilt it 4 years ago.. starting to think that rod was bent the whole time as I always had a cylinder that didnt like to fire when cold.
