Default What Springs for Jesel Sportsmans

I'm revamping my valvetrain and I've got a set of jesel sportsman rockers (Non adjustable) I'm going to use. With that said my pushrods are going to be 11/32 manton pieces have to measure for length still but I'm looking for valve springs.

I currently run PSI 1511 springs but I know those will have to change for some kind of duals. I wont really have access to a dyno after the swap so I need something thats going to work with no question of valve float (providing proper setup). I shot an email to tick and btr but havent heard anything. I just dont want to call because those guys are busy and I'm not ready to buy right at the moment.

Kip told me that they use the BTR normal duals with the jesels, but after I got off the phone I realized he was talking about the adjustable jesels and also on solid rollers which I imagine have softer lobes than a hydraulic cam.

Oh and the cam grind is a futral f13 230/232 .595 .585 114lsa ground on their newer softer lobes

The person that specd the cam should be able to tell you the appropriate valve springs needed for your application.

BTR .660 springs will be perfect

The BTR duals should be fine with Ti retainers. What lifters are you running? A solid roller, even tight lash, usually requires more valve spring than a hyd setup. Kip has designed some nice setups that use a good but economical spring kit and they are stable. PAC has some nice offerings if you want more lift/rpm capability. The Jesel rockers can handle way more spring than you need anyway.

Thanks Kip I did not mean to question your expertise it just occured to me when we pm'd that I'm not using the jesel adjustbles like you are, mine are the sportsmans which arent adjustable. Also I figured the LLSR lobes were smoother than the futral lobes so the btr springs may be fine for that but I wasnt sure about a hydraulic setup.

Ya im still using a hyd roller just going to a better valvetrain so the spring choice should be a little different than a LLSR but we'll see
