I have jessel ss rockers they are non adjustable. If you don't want to spend a ton then jessel is not the way to go. try looking at the new harland sharps or comp cams i think those are adjustable and look pretty good.

Looks like it says there adjustable. Maybe they have changed the design since Tuff purchased them? I would just call and confirm with Jessel before ordering. They look nice.

I was looking on SDPC's site and they said theyre adjustable, but I remember seeing on another vendors site saying they were NOT adjustable?! Maybe they have adjustable and non-adjustable?

They look like nice rockers. Did any have to elongate the pushrod holes?

There are adjustable and non-adjustable 1.7 ratio versions. The non-adjustable SS Jesels are available from MTI:
Jesel SS Series Roller Rockers (non-adjustable) $695.00

I have them on my 427. They're VERY nice pieces. You'll have to remove the baffles for the PCV in the valve covers to get them to fit the stock valve covers.

Thats where I seen it! The adjustables and non-adjustable are the same price though. Did they fit under the stock valvecover with out the spacers?

Thanks Levi

Country Boy: what is your setup that is forcing you to go adjustable. I am asking as I am wondering if I will have to go adjustable too. I will have a TR236 cam, milled TEA heads with 2.055 intake valves. I will also have to fly cut the pistons to get PtV clearance. I am thinking I will have to have adjustables to get the correct preload with all the valve train changes.

I am thinking about your CC Pro Mags but I am not sure the extra .05 of ratio will out me last the edge even with fly cutting the pistons.

The adjusables need valve cover spacers. The non adjustables like i have you just need to gut the baffles all out and grind some of the casting bosses.I never had a pushrod clearnce problem.

I have the Comp "R" lifters which need a very light preload hence why I needed adjustables. I have to sell my CC Pro Mags because I cant use the extra .05 ratio. That would make my lift really huge for a 346 motor.

Yes, mine fit w/out spacers, just have to remove the internal PCV baffles inside the valvecovers

I have comp r lifters and when i setup my pre load i just bought shim stock from ace harware and drilled holes for it to go under the rocker mount bar and that took care of my preload problem.

THANK YOU!!!! There is hope yet Talk about money pits I was hoping to not have to spend ~$250 for a couple pieces of aluminum I use the LS6 PCV so I can gut the covers.

Ive never been a fan of shimming the rockers. You cant get it right, just close 99% of the time since ships come in intervals

Push Rods come in 7.40, 7.35, etc and differ by .05 in lenght. How is using a .030 shim any worst than that?

Country Boy

iTrader: (24)

Its not, hence the need for the adjustable rockers to get it right. Its good if the preload is an even number like .005, .010, .020 etc, but when you need .002-.004, the shims dont work. Also, when you add a shim under the rocker, you change the valvetrain geometry slightly.

Hey Cannibal,

Which Jessel's did you install, adjustables or non-adjustables? Do you have a part number?

Thanks.
