Can someone tell me what compression ratio is safe for 89???

I was assuming you were running a head gasket with a 4.370 bore. https://cimg7.ibsrv.net/gimg/www.off...4268d7cfc8.jpg

I'd look at these in the 320cc version. https://www.offshoreonly.com/classif...ds-o72091.html

Hey Griff,
This ad for the EQ 320's is gone, do you know who was selling them, assembled I assume?

Thanks

Competition products also sells them assembled. I am pretty sure they will put whatever valves and springs in them you want also.
