any suggestions on porting and boring? i plan to get comp cams stage II's and valve springs, but i have no idea what to ask for as far as porting and boring. i want to open it up and still be able to add a sc. what sizes should i ask for? i have a 99 gt sohc.

if eventually your going to add a blower then it would be wise to invest in a forged bottom end, but as far as the heads go you can get the heads port and polished and since they are Comp cams that your installing the springs will have to be swapped out.
