    Suggestion I would build your future block for water/meth setup you'll be happier with it if this guna be a track car lowers intake temps etc and allows more higher compression to be used vs e85 but that 9:75 sounds like a little to much on iron heads with some boost. It can work but u need a bigger cam than the vs or xp wit a lot of duration to bleed off the cylinders.Aluminium heads with the xp cam would work with thermal coated pistons .

    But basic forged pistons with the ring end gaps open up a little more for the boost would work too

    YES! open the top ring gap, and forged pistons are great as long as the proper piston to wall clearences are met, and then they still might make a
    little bit of noise.
    BUT again, the most important part on ANY boosted application is the
    TOP piston ring gap, that is why so many STOCK engines blow up by
    breaking the top ringland OFF!!!!!
