Big block Chevy
Ok yella terra rockers are 1.7 one valve and
1.75 on the other. Each pair has a number on
the 1.75 side. I have 2,3,4,5,8 and one without
a number that I believe is #1 because I know
#7 is where I had a problem

Might have to get one more tie bar as it looks
Like one is ground by the original bs
