Both cams work on a 114, with no milling on the head save for a MINIMAL cleanup of 3 thou MAX, and a 2.02 valve. No larger. You'll have 70 thou on an x3, and 85 thou on an x2.

The x2 on a 112 will work as well, but ptv is decreased to ~ 70-75.

X3 on a 112 will fit in a 100% stock headed car, but ptv is tight. Its not something we reccommend on a daily basis, but for those that want to push the limits, it will fit.

Anything more than a stock head will require flycutting on the X3.

hope that helps

About what would the ptv clearance be on a stock head car with the X3 on a 112? Just a ballpark figure would work. I'm debating between the X3 and X2.

 

How about g5x3-114 and Absolute Speed's stage 2 5.3 heads the new design????????

 

So a X3 114 won't fit on a 100% stock LS1 heads? I just want to slip the thing in and go get it tuned...

 

Yes, fits perfectly with stock heads, I am using it right now
