altec

I have a 1994 LS B18b1, i bought the car a year ago form a friend, car has 150k on it 60k of that i know for a fact is all highway miles, but nonetheless it has 150k on it and i was looking into port and polishing the head, i do plan on a turbo set up by next year, problem is ive heard alot about ls/vtec engines that produce amazing torque and hp, not sure if i should port and polish the stock ls head, or if i should look into spending the money towards and ls/vtec......looking for any opinions and or website, that would have more information to what i would need or should do......SORRY if theres a post about this and i missed it......If LS/Vtec is the way i need to go i can always push the turbo back for the funds...
