small block indy heads

Indy's castingd do suck , but the leaking issues are from them being too thin. This usually happens in the exhaust port after heavy porting. Their own CNC ex port program is one of the biggest offenders in regard to this issue. Of course if you call them out on this they'll tell you they have the best castings in the industry, and have never hears of this problem. Lying *** mother phukers
