Installing 98 cobra cams

My engine builder is currently installing my 98 cobra intake cams.
He's telling me the intake is coming in at 119 on center and 114 exhaust on center.
I have searched a lot.... I have seen both 114 / 114 listed and 119 / 110 listed... this is for an open track application 2500-6000 rpms
Which is correct?
Please help

Are you running adjustable gears?

You need those to get them dialed in. If not you can slightly trim/shave the keyways. There are a few factors that can make them not drop in to what you think they should. Shaving the heads, blocks, valve cover gasket thickness are a few big ones.

It's all been here for a couple years now:

I have timed many at 108 intake and 114 exhaust. Blown and Na. Peak hp is right at 6200 rpms.

thanks everyone, tuner was finally able to dial it in 100-114, required comp cams adjustable gears though

100? I usually shoot for 110 ~ 112 intake for similar setups.

107* is going to be a pretty tight LS

typo, 110/114
