ProComp/Speedmaster aluminum heads

Going to try and put motor and trans back in tomorrow.. not 100% happy with the idea of dangling the motor and that heavy trans from the aluminum heads...

Don’t you have a scatter shield? I’ve never been able to stick a engine/trans together when there is a big scatter shield on there.

As long as you have at least one times the diameter of the bolt into the threads on the head the aluminum will hold much more than the weight of the engine/trans.
