My new B1 heads should be ready for Koffel's to set up with rocker gear pretty soon and I need to decide between Jesel or T&D rockers. Has anybody here used or at least had some experience with both?

I am in the market as well....maybe we can get a deal if we buy two sets

I have a set of each on 2 different cars and no complaints on either one....I do know that Jesel charges alot to rebuild there's.

I use Jessel individual shaft and have single shaft T&D's on my other motor. The Jessel's are really nice, and so are the T&D's, but the individual system is by far the best. The Jessels require alot of machine work, and the T&D's don't. That would make my mind up.

Jesel is about as good as it gets. They also allow for large diameter springs which the T&D in some cases do not.
I would advise going with pushrod oiling also. I ran spray bar oiling on my engine, and had no trouble. I actually made my own spray bar/lines setup.
If starting from scratch I would have had the Indy Maxx block drilled to allow pushrod oiling. But my machine shop couldnt do it.
The spray bar covers and setup isnt real cheap $400+ so the costs of having the lifter bores drilled should actually save some money. The push rods are Not any more money with the oil holes.

If you are interested in making your own spray bar lines..I wouldnt care to share how I did them

I think it might take more than two sets. Anybody else interested? Maybe an early

Hey Bob, would or wouldn't? Sure would like to see.

T&D individual shaft is the best option IMO. Been working for me with zero issues. BTW fwiw my springs are 1.677 diameter and the rockers clear with NO issues or clearancing and i pushrod oil as well.

As told by a guy who used to work at T&D, the Jesels use a "spray and pray" oiling setup while the T&D's have pressurized oiling from the adjuster to the trunion bearings.
I don't think you could go wrong with either set.

What I meant to say is, I run the Jessels and they are pushrod fed oiling individual shaft rockers. They work great, but required alot of machine work to fit. I also run the single shaft T&D's and they worked fine, once the pushrod length was perfect, and I mean it needs to be perfect. But when I build my next rocker system, it will be with T&D individual shaft system, because they don't require the extra machine work that the Jessel's do. I have also used the Koffel black rockers, and they worked fine for me. I did order the torington bearing kit from Tom Hemphil for the rocker shafts. He is in PA and can help with that. But if you are set on individual shaft system, pushrod oiling is the only way to go IMO.

Do the T&D rockers that require no machining need to oil through the push rod?

My vote is the T&D individual shaft rockers. My Engine guy Tom HEMPHILL ordered the Jesel & got to looking what it would take to make them work & decided to fall back on the tried & true T&D that he has used for years on B1 stuff.
One thing to watch for is when you install the rockers make a few pulls & check to be sure the rollers aren't locked up. Mine were soaked in oil for a day or two like the instructions say & 3 were stiff & it scored the roller. One had to be replaced the others were removed, polished & reinstalled.

GOOD LUCK

We've had great luck with Jesel's.

Sean, Koffel's still has the heads so I was hoping I could just have them do an "upgrade" to the Jesel or TD setup and get them to adjust the pricing. I mentioned to Scott when I ordered that I might want to go this route, don't know if he'll remember.

We broke a rocker on the Indy set-up we ran last year and now we're paranoid. That's the biggest reason we're switching heads. Figured if we had to spend money on better rockers it might as well be on better heads also.

I know Koffel, along with a lot of other people use the standard B1 rockers without problems. That's OK for people who have the resources to fix broken parts and go racing again the next weekend but that's not me. At my stage in life and with the money involved, if I grenade this motor I'm probably all done racing.

Seriously, you could flip a coin on the rockers. Since you're in Oregon I'd consider T&D's just because if you do need parts, they're only a state and a half away from you.

Pay now and get the good stuff, have Koffels do it for you now so you don't have to pay more later when it breaks, if if(the black rockers) ever does

HOW MUCH MONEY ARE THE T/D AND JESSEL SETUP
