Has anyone used Time-Sert steel inserts in a 4 thread head? Success?
Time sert said they only recommend the aluminum insert if you are running fuel. I thought the same. Talked to time sert and a supplier of their product. Said they use only the steel ones without any problems. I asked about hot spots with the steel, again no problem. I have the kit coming, but I can order the aluminum inserts separately. Hoping someone here has used the steelpretty sure you're supposed to use an aluminum insert in an aluminum head, I'd be kinda surprised if they actually offer a steel insert for a mod motor.
Time-cert is a quality product. I believe my builder used Lock-n-stitch
