Hello All, The more I look @ this 75 Block I have, the more I want to use it. The oval water jackets on the 75 block do not appear to be sufficiently covered by the metal around the round jackets on my 72 heads. How do I solve this compatibility issue? Gonna start assembly first of next week. Thanks, tom.
Tom Just make sure to use composite gaskets and it will be alright as long as the hole is covered by the head. It doesn't take much to get a good seal. I have been running '69 heads on '75 and '76 blocks for 10 years without a problem. Mike
there is no issue, it works, in my 70 GS, i run 70 heads on a 76 block. there are issues when you try to put late heads on a early block. ,
