hey guys i am rebuilding my vette engine as we speak and am getting ready to throw the heads on. the lifters i ordered at gm p/n 17122490 and have the entire roller covered by the lifter "skirt" while the stock lifters I removed do not have the roller covered (it is completely exposed).

do I have the right lifters and will they work OK with my GT11 lingenfelter cam???

thanks

Yes they will work. That lifter is used in 4.8,5.3,6.0, and 7.0 Liters.

Thanks. I am asumming that the GT11 duration/lift won't hurt or interfere with these "skirts" covering the roller on these lifters?

Your new lifters are an improved design. There were some breakage problems with the earlier design that you are replacing. They are fine with any cam.
