I am going to to run a "RV" cam...believe machine shop said the cam was 422 intake....444 exhaust lift. and the advertised duration is .278 and .288. Will these heads work well for my needs? 87 w100 Ram work truck. Should i just keep hunting for 360 heads? What can i expect for comp? I know 360 are gas hogs but will these heads help or hurt?
