406 Vette
SBC 406 Mock up to verify deck height and stud placement.
I used ARP head studs and MLS head gaskets hoping to hold the gasket between the siamesed .030" overbored cylinders better.The block was "0" decked and squared to the crank, leaving a .040" quench from the head gasket thickness.Studs installed finger tight and backed off 1/4 turn,the bolt holes are open to the water jacket so I used some Ultra Black RTV on the threads at the time of assembly,inside washer concave towards the nuts{12 point}.Head Torque,70ft.lbs. with ARP Moly Assembly lube,in four increments, 10ft.lbs.,30ft.lbs.,50ft.lbs.,70ft.lbs.,rotating through the sequence until all nuts took a "set" at each increment,the MLS gaskets have alot of "squish" to them at the lower torque settings so it took quite a few times throught the sequence to pull them down as even as possible.
