Valve keeper angles ?

[drsportster]

Are Most Valve keeper angles the same? Meaning the tapered part the goes into the retainer . If your valves have four grooves will any four groove keeper fit or would you possibly get a mismatch at the taper part Just curious as I have eBay valves that need keepers Exhausts have two grooves and intakes have four grooves .

Different engines have different size valve stems, you would need keepers for what ever size valve stem you have.

I googled it and got educated there are three taper 7 degree normal very common then 10 degree High performance called Jumbo then an 8 degree hybrid

How do you decide which taper you need? .....I assume they will have to match the taper in the retainer?

 

[drsportster]

Most likely a 7 degree but yes they must match the retainers angle

The 8 degree hybrid is one I’m not familiar with
7 degree as been the industry standard for years
10 degree keepers helped eliminate keeps pulling thru or splitting retainers on performance engines with high valve spring pressures

What were you originally trying to do? Are you fitting oversize valves in something, or trying to find a non-oem valve that will get something where original parts are obsolete going or what?
