Locks can cost you an engine, no joke. I buy good locks and retainers. Hell, springs too. I dropped a valve once, my stupidity for not keeping a better eye on things. When I measured the spring pressure they were all down 40 pounds from new. But, some of that was simply from the titanium retainers getting eaten-away. They were so damn thin, almost razor blade thin, I couldn't believe it! When I checked the springs they were actually only 20 light, the rest was gone from the spring seat and retainer. Well, over-rev the thing and caught an intake. I think that was a $5k bill to fix it all.

Brandywine Cylinder Heads in PA, they did an incredible job making those heads look brand new. They will always be my go-to place for a major repair. Wish I could find the pictures. They say they can even rebuild a missing combustion chamber.............

Fox, buy good locks, seriously, do not use that stuff! If you do not know if their retainers are good stuff, look at titanium from a good supplier. Yeah, they run about $300 now. You really don't need titanium, tool steel will be fine also. You can not take chances on those parts.

I like tool steel because it doesn't wear like Ti and it's almost as light, but my engine guy is telling me to go Ti anyways. We don’t always have to agree, lol.

You want to borrow my Moroso compressor? My wife just used it to take her heads apart. I bolted the head to a 2x12 which I clamped to the top of my bench,. Easy-peasy! And the valves can't fall into the engine. Very simple to do.

I put paper towel or whatever under the valves to stop them from dropping when trying to fit the keepers
 
Back to the earlier conversation about pushrods. I’m using 5/16 .118” wall Manton’s with upgraded tips. I believe I spoke to Matt over there that set me up.

Toby recommended that I go 3/8”, but I already installed the 5/16 and I’ve been running them. They have been seeing 7,800 to 8,000 rpm through the traps.

I will send you my LSM tool as long as you send it back when you’re done. After seeing how chewed up those locks were I wouldn’t use them.

My LSM tool is great, but only works on my T&D shaft rockers. The Moroso tool I have is pretty good, and works with any 3/8 or 7/16 stud.

I have 5/16 on the wifeys engine. I run 3/8 heavy wall stuff on mine. Some heads do not have the room for 3/8.

What's the LSM tool for your heads?
I'd be willing to chip in for one of them.
You've afforded us a great deal of entertainment!

I’d have to go to the garage to verify, but I think this is the one I have. I also have the Moroso one.

Shit, that looks like mine, but there's no model number on it.
Mine is for a BBC with T&D rockers.

OK, Interesting. Sell me on them, anyone?

I can see the format of the first one being handy for on-engine, or as Mike said, head bolted down.

The 2000... big bucks. Must spin nicer than I imagine it to, because after using an over center lever type, I can't imagine wanting anything based around threads. I don't do this much, but I'm hyper-specific on if a tool works for me or not. Kind of shocks me the threaded thing...

This is a different model, but they work the same. These things work like butter, I’m not really trying to sell anything, but I’ve tried a lot of different spring compressors and the LSM is the one I like best. I’m not sure which threads you are concerned with, the ones on the heads or the ones on the tool. Neither of them are an issue.

LSM makes killer stuff. And honestly, for the quality of their products their pricing is very reasonable.

Baller, lol
60° stub thread I assume, like we use on steam/pressure piping valves.
 
@Patriot Racer to the rescue. Need to figure out what locks fit and order some. Not sure how to find that out but I'll make some calls.

@IADR @Mike Beck thanks for talking sense. Clearer head prevailed this morning. Cheap insurance.

@DHR Darren it's dot to dot you whore. Happy belated birthday:20250627_100218.jpg

Seriously, where are you located?
I'm sure if someone is close, they would help with removing the springs.

I have this

Client Challenge

Price sure went up since I got mine!

Edit: don't know why it says client challenge. It's the proform tool.

@Patriot Racer has saved my ass I cannot count how many times. He's been to the post office about 7 times the last 30 days sending me miscellaneous stuff, parts, tools, hardware, you name it.

Patriot Loaner Program is in full effect so I can get the locks changed. This forum has changed my life. Made me bankrupt, but changed my life!

The only reason I initially signed up to YB was to ask a guy what backspace and suspension he had to make his foxbody look so good.. and now look where I am
