Remove a couple of cylinder head bolts, and make brackets from angle iron to bolt onto the engine, using those head bolts. I use bolts diagonally opposite each other, front and rear. Then bolt your lift chain to holes drilled in the angle iron. Be sure not to bend pushrods or other components with the lift chain.
