i was at a shop today asking for a price for a sohc vtec head for my civic. and the guy told me i should instead get the head that's already on there port and polished, put in a race cam, a header. and new fuel pressure regulator and the car would be really good. i asked if it's ok for daily use, and he said 'yes'. i never really heard of doing this to the stock D16Y7 cuz it's already a weak engine, but he said it's strong enough to take it. is this info correct? and if so, how will my gas milage be? cuz this car is my daily driver, and i need it to stay with the good gas milage it already gets.

he gave me a price of $1500 (labor and parts) for everything done, but i would just buy the parts and do it myself anyway, so he said $300-400 for just the cam.

am i better off just sticking wit my orignal idea of getting the D16Y8 head ?

(please dont tell me to swap, that will be sumtime in the future, im gonna just keep this motor for now and do work to it)

thanks in advance
