If you place a folded shop towel under the valve faces it will keep them in a better position

Good stuff. Your valve job went way smoother than mine (I was using harbor freight junk spring compressor). I had to fight and fight to get the spring retainers out! Anyway since you have it apart, put a little lapping compound on the valves and lap them to the head for better seal. I just chucked mine in a cordless drill.

Thanks for sharing! I received the btr valve spring compressor tool today and I had the same question on which way to orient the aluminum plate that you place on first. 👍

Fack men I never leave comments but this was hella helpful 🤘🏾

I've wondered since the 1st time I saw one of these, what that eyelet is for lol. I wish I had bought one of those compressors just to be quick. I broke Orielys on 1st 660 spring lol. So I made a great one for the bench out of a 12" clamp and welded the 13/16" spark plug socket you never use onto it. cut a window in the socket and it will clamp 400# spring with just finger pressure.

The only thing I highly recommend is valve seal fitting sleeves. $6 bucks to be 100% sure the machined sharp edge of the valve does not scuff/cut new seals.

Haha I was going to say I think you forgot something, but then you caught yourself 😂😂

The cutouts on the tool is for if your using larger springs like the beehive springs

Where did u find this tool?

Is the small gap between the seal and retainer normal on a dual spring setup?
