73 Duster....milkshake ****

If you ran that milkshake I would be replacing all of the bearings too. Antifreeze and bearings don’t mix.

This is not my 1st milkshake....i will clean and flush the engine ....
This 360 is a MP crate 360 ....90ish LA roller block....020 over with seal power 116hcp pistons..low compression model....

Dont think a head is cracked...think it was the intake manifold..but I was thinking about changing the heads out anyway...
