I use thick tin between my intake gasket and head as i was told by the tech guy that pouring in is prohibited

Correct, I was under the impression as long as it does not protrude into the valve pocket you are OK. Exhaust runner volume still needs to meet minimum spec. Not sure how you would measure it it if was not filled.

Adam good to hear it is worth power.
