Guys can it be that the wrong head gasket is the reason for a water leak on on passenger site between the head and block.
We notice it on the engine stand.

Heads are 4# 330
Block 350 68-70

Gaskets are the same. Did you torque the bolts properly in the correct sequence.

 

Yes

 

Did you have the heads and block check for straightness? and were you very clean about how you put it together and prepared the surfaces?

They take the same gaskets. Should fit perfectly. 4 heads are in my opinion a great head that is way overlooked when it comes to Olds Small blocks.

 

Problem solved.
Thanks

 

Care to elaborate?

Not property torqued bolts - dead torque wrench
