The exhaust must be able to float with the engine vibration & movement. If the exhaust system is rigid that may transfer to the headers and header bolts. Use flexible couplings if you have to. For heat cycling, remember you must run the camotor for at least 90 seconds at WOT in top gear each time you get it up to temp -regular maintenance rules still apply.
