the chamber size i have only seen with the pro comp stuff is 120 or 115 cc chamber head? i would have to look your number up. i did not do that but . you will need a small dome for the cc of the head chamber to get to 9to1 . head gasket fire ring size and if in the piston are in the hole abit that plays in to it as well .with a flat top with a 3cc valve cut your going to be 9.7 @96.5 cc ..8.4 cc @115 cc and 8.2 @119cc .so if the new pistons in the hole about .010 and head gasket is 9.5 cc .039x4.370 bore =9.5 cc with a 18 cc dome piston like icon #ic779 .190 dome you will be at 9.3 . so no them heads will not work with flat top as they are for 9to1Last edited by pat mccarthy; 02-03-2013 at 09:04 PM. Reason: looked up procomp head number
