ive searched and i cant get the info i need(if im searching wrong inform me please)
.i want to know what i should do to my LS head if im gonna be boosting 10 -15 psi..?
should i port and polish it? should i leave the valvetrain alone or will dual springs and maybee turbo specific cams help me....?will it be a waist at that much psi..any feedback will be appreciated..

 

You are talking about upgrading the wrong part of the engine. To boost 10psi all you need is good management. To boost 15psi or higher you should consider a block gaurd, better pistons, etc or sleeving the block if your a baller

 

i knew i should have said something about that first .....thats all getting done up...i know what im gonna do to the block...(sleeved, forged internals ,whole nine yards...im just at the head now...i dont want to short change myself by building a bullet proof bottom end with a weak .head...if im not mistaken wont there be valve float if i dont get stiffer springs@15 psi...(remeber LS head)
