Re: 8BA valve retainers
The actual valve spring retainers are different between the two styles of valves. The NON rotator valve uses the 8BA-6514 spring retainer.....this is considered the "one piece" type retainer. The factory valves are 8BA-6505 and 6507. The springs are either the 78-6513 or the 0BA-6513 which are interchangeable.
The ROTATOR type valves use a two piece spring retainer......the 1BA-6514 retainer and the 1BA-6517 sleeve. The factory valves are the 1BA-6505 and 6507. The springs are the 1BA-6513 which are shorter than the 78-6513 and 0BA-6513.
Both valve setups use the same split keepers, the same valve guides, and the same guide retainers. The rotator type valve components are not all available anymore. We stock the valves, the springs, and have a few sets of the above mentioned spring retainers for those who wish to keep these in action. Our kits, however, are the non-rotator type valves.
Hopefully this helps explain things for you.
