Yes, it'll work with an LT1 cam as long as the block has the provision for the roller lifter retainers, cam retainer plate, etc., already machined.

(I'll have to admit I'm having trouble understanding what you're asking.)
If the nubs in the lifter valley have been machined flat on the top, drilled and tapped; and the tops of the lifter bores have been machined flat; and the front of the block where the cam goes in is machined flat and has holes drilled for the cam retainer plate - then yes, you can install the LT1 cam with the retainer plate, and the factory roller lifters with the dog bone anti-rotation plates and spider dog bone retainer. Use an '87-'92 3rd gen V8 timing set.
Be aware that the factory used two different spacings for the cam retainer plate bolts (and I hope you got that with the other roller lifter stuff you got). I got my roller lifter parts from an '87 LB9, to put in a early-90's ZZ3 block, and they were of the different type. I elongated the bolt holes in the plate to get it to fit.

Re: Making a roller block?
Ya the block was from a 88 firebird but was flat tapped when I got it for done reason....anyways yeah it had all the things I assume to use the roller stuff the cam retainer plate bolted right up so I'm guess ibf its ok to use it....i didn't change the bearings in the motor I left all internals inside of it. Thanks for the help I was a little confused a little bit...m my dumb friend told me I had to change my cam bearings and stuff.
