I,ve cleaned the whole thing and test fitted the manifold and ther is no preceptable 'rock'...
Are these big stroked 351s in need of very special intake sealing? Gong to talk to the builder tomorrow.
Really frustrating.
I am thinking studs would be better?

Sorry to hear this...my 427sr intake let go last year. Bolts were loose.
When I fixed...I torgued the intake bolts in the proper sequence likely 20 times before they didn't need a touch up of torque. And didn't drive super hard until the torque was stable.
I used a thread compound that is suppose to help keep torque (not lockite). I can try to find it for you.
