Replacing cylinder heads BB Chev ??? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

It has been years since I have done this so I have a couple ???. I have the trusty chilton manual on hand so I know the Tq specs and the order to Torque the heads down, however... is it recommended to tq the bolts down working your way up to the final ft Lbs? Or should you just go to full Tq starting on the first bolt and do them all like that?

Also when the time comes to replace the intake manifold is there any good tips for getting the 4 pce gasket set to seal well? I have some High temp silicone for the 4 corners and around the water jacket holes. Any advice would be great as I dont want to do this over should I miss something simple.

Thanks

Curt
