yeah I know bolt em on the engine LOL

I have o-ringed AFR 210s (pro ported by Agostino Racing . . . being sent to advanced induction for some real work)

do I just silicone the waterjackets? do I need something else?
I was told I don't need to machine the block to use em

any info appreciated
thanks as always

I can only offer a second hand opinion given to me by my engine man. He cuts a receiver groove in the block and installs a steel O ring and uses copper gaskets.

there is a story in the current issue of pontiac high performance on how to do this. David
