The value of a Turbo head with ceramic lined exhaust ports and heat resistant valves is way above that of a normal unit. (Price the valves.) There would be no advantage performance wise. Also check the machine specs on head thickness. Could wind up with low compression. Valve springs are cheap and even oversize stainless valves are far less than the original Turbo parts and could yield better breathing.
