need measurement on stock "J" head

it all helps ...LOL

I just went and mic mine and it looks like BJR knows what he is talking about ...LOL thanks
Mine mic .967 .974 .971 and on the other head .973 .977 .968
and I know they have been cut .030 at least but the machinist that shaved them for me 30 years ago died and we couldnt read his stamping on the head..guess I will find out if its been cut too much when I go to install the intake and deal with it then ...LOL
