gude head package

well this question is for any one running this on their integra, vtec or non.
I know allmotorls has ot on his integra which is putting down 160 to the wheels… but i heard alot bad things about them, so if anyone wants to respond to they’re defence or post dyno sheets or something to prove the package does make power please do, because i want to try it out but don’t want to disappointed either
