If you go solids you would want to get a checker for the correct lenght to keep the roller rocker in the center of the valve stem top from the start of lift through max lift. This takes side load off the valve stem. For head gaskets, I use the Fel Pro 1020's. I modifiled them for all the holes to be open to the block and head. I high tac them on both sides or Indian head shelic. Tork the heads to spec, the head them for 1/2 hour back off the nuts and reset. Have not had a problem doing this. You can use bolts from ARP. I like the stud kits better. Use Anti Seize on all the threads going into the block. Put a thin coat on the washer that goes under the nut so not to damage the mounting surface on the head. Tork the head to 30lbs. and then go back in sequence and add 10 ft more to tork wrench under spec is reached. Smith brothers make custom lenght pushrods and you will have them in 48 hours. I would make sure that you use heavy duty rocker shaftsif you go with the stock system. Get aftermarket end support mounts for the shafts. I just broke a standard one at R&G, ripped the helicoil out of the head and it ate the aluminium and stuck to the valve. I have 2 dead cylinders right now. I am going to replace the helicoils in may heads with timeserts and go to a larger stud to hold the assembly to the head. I run a small cam 501-533". The Edelbrock heads have the T&D setup on them. This is alot stronger setup, more machine work, and need lifters to pump
oil to the rockers. Rick Lake
