The LS7 lifters are the same dimensionally as the LS1 lifters. OP you should be fine unless a lot of material was taken off the deck of the heads. Still wouldn't hurt to check though if you have the means.

As for goals i want a d1 procharger eventually but as we all know parts are expensive as hell
it took me almost a year to accumualte this little bunch lol and before i do the procharger im going to do all susspension ie tubular k member upper and lower control arms all that stuff then im going to get a clutch and a rear and finally the procharger only thing im worried about is maybe loosing a little power with the lower compression from these heads but we'll see how it turns out soon

I agree that it never hurts to check, but the LS7 lifters are direct replacements. If you button the motor back up without swapping anything but the lifters, new pushrods would not be needed.
