Hard blok filled b block question/ coolant hose to back of cylinder head.

Yeah I can see it now, thanks for sharing and telling me what to look for. I know it's 1/2 the state away but do you ever head east to renegade raceway?
I used to run dad’s car over there for the hotrod drags. But that was 30 years ago. I hope to get over there soon. Not sure the new motor will be ready for ‘26 or not but I am trying.
