is it worthit to upgrade my supra with stock turbo?

[fantasma87]

thank you grandavi and btwilson and the rest that comment on my post. thats why its important to ask questions or listening to other people ,they may save you time and money on a problem. THIS IS MY DEAL, i will remove the engine and tranny with a friend at my house, i live in Kansas and around the area i havent see any auto shop capable of doing the head. if compression its good and i work with the valves and give a good clean on the block and gasket , it will be ok to replace the gasket with a normal one rather than the metal one? i`m planning to boost it up a little more, not for racing but to feel the joy when i step on it , "short trips"
