The Fuelly heads are 64CC . But after the clean up cut they most likely had . They are at 62CCs . They will work good . Use a .041 head gasket . You should be just over 9.5.1 . Only thing with the fuellys is most of them do not have the Bolt holes in the front off the heads . What # heads are they ? The #186 and #041 heads have the bolt holes . You most likely will have to run 89 Fuel but you will have more power . COOL
