If this is a stock Motor You can go back to the Fiber gear which had a steel center. But It will not hold up to any Type Of cam change.(meaning anything above stock)
Hank at one time Cloyes did make a all steel set.Which they used to sell to UPS. But are no longger made.!( I got the last set back in 84 in which i still have NO not 4sale)It is also my understanding that PES sold a straight cut Steel gear set If they still do I don't know.
But anyway 6T4 if the ALum gear set is installed The right way You won't have any issues.Like you just had.
God doesn't like ugly.
