    Has anybody had problems with the combustion chambers collapsing on AFR 227 Heads when they are used in a supercharged application?

    I used them and I had no problems with them denting the chambers but I wasn't putting a huge amount of boost to them.
    What do you plan on using for a blower and how hard are you going to drive it?

    Our Boost is 30 PSI on methanol with 8:71 and hat. Have wrecked two sets of heads with no sign on detanation on the bearings. Used AFR 220s with no problem. Car runs 7.60.
