I ordered them for my 1970 Olds 455 engine a year and a half ago, but have yet to use them. I'm not sure what other engines they'll work with. However, if you go to a store like Jegs or Summit Auto Parts, they should be able to point you in the right direction.

I only got 15 keepers instead of 16, which is inconvenient when you're in the middle of a project and have to dig through your junk drawer to find the parts you paid for but were screwed out of. I didn't realize I was shorted until I was down to three valves, which meant the job was nearly complete. I could only get a refund or a replacement if I returned the items to Amazon. I'm not going to rip the heads apart again just to get a refund for one keeper. It's a complete waste of time.
On time and exactly as described. It was simple to install and has performed admirably so far.
It's quite effective.
On a 1990 F150 302, this part was used to replace the stock keepers. They were a perfect fit for the original valves.
item exactly as expected.
Thank you.
Fit great.
