Stu I don't like what I see from CME ... first thing is the piston choice ... junk KB pistons ... see the thread about a 383 that is currently running.

They don't tell you what heads cores they are going to use, so unless you supply them with something it sounds like you are going to end up with open chamber iron junk. For what they think they are going to charge you for redoing those heads they could buy a set of alum heads , like sidewinders , that are ready to go and you end up with something that flows better ... more HP ... and is more pump gas friendly.
