The question is this: Is it ok, or a bad idea to change these bolts from the standard grade 5 to a grade 8 bolt? I'd like to hear comments both good and bad. Have you had a broken head bolt? Tell me about it friend.
Also, can anyone tell me the proper length of the bolts ( or length of threads, or anything the makes the bolt special ) that go on the cub head? The engine came in a million pieces when purchased.
Thanks for your time.
