Eddy head question

You can put a bolt in the head and lift the engine just make sure the bolt is threaded into the head 3/4" to 1" not less than 1/2".

Adjustable rockers are needed to get the pre-load on the lifters set correctly. However, if your push rods are just the right length you don't need adjustable rockers. What you need to do is check the pre-load of each lifter by rotating engine and putting cam on the base circle. With the intake off and using "wire" feeler guages you can measure how far the lifter plunger is compressed. For most lifters to work correctly they need to be compressed .010" to .030" inch. If they are compressed too much the valves may not seal and it could cause the valve to lift too much contacting the piston although you prob won't have that prob cause it sounds like you have a pretty mild cam. Either way I would check that preload and if its too much or too little you will have to switch push rods or get adjustable rockers.

I run Felpro 1008 head gaskets which Edelbrock recommends and ARP head bolts and I did not retorque the head bolts. Probably should but have not got around to it and its been a few years....
