Re: rebuilding lt1
Sure, the Hotcam is "good". But the kit is overpriced, and the springs it comes with aren't sufficient to control the valves at the revs the Hotcam wants to be shifted at for best performance. You'll want to use the thinner .026" head gasket to boost CR to work better with the Hotcam.
500 hp......not a snowball's chance in hell with the Hotcam. More like 400 .. at the crank.

Re: rebuilding lt1
Just a "cam" is not your route to 500 hp.
You need to do a lot of reading to get a basic understanding of how this all works before anything that anybody on here says to you is going to make sense.
Start here (it applies to the F-body LT1 just as well):

Don't be lazy.
"You need to do a lot of reading to get a basic understanding of how this all works before anything that anybody on here says to you is going to make sense."
If you don't heed that advice, you're doomed to failure. And it will be an expensive lesson if you're bound and determined to order parts now.

Budget at least $2000 for parts, machining, and professional labor to rebuild yours or buy a really stout shortblock for ~$5000 from somewhere like here:

The problem with 500 horsepower is the collateral problems you'll encounter. Your rear can't handle 500 HP. A new one costs $2500. Your stock suspension will hop, twist and otherwise not get the power to the ground. You'll replace the lower control arms to the tune of $500. Think that trans will take the torque output of a 500 horse engine? Nope, a high performance build is in your future.
500 horsepower sounds great and it's great when bench racing but you aren't going to build a good 500 horse car for $2000 in parts and machining. Believe me, it's closer to $6500 if you do the work yourself...way more if someone else turns the wrenches.
There are lots of guys on here that can help you with your choices on how to build a 500 horse engine. I just thought you should look at he bigger picture.

Re: rebuilding lt1
Are you looking for 500 HP at the flywheel or at the rear wheels?
Are you figuring a naturally aspirated setup or a power adder (turbo, S/C, nitrous) to reach your goal?
Then start with the heads, not the cam.

Read the link posted in post #4. Presents what you need to do in a perfectly logical progression. Air in.... exhaust out.... beef up the engine components that control the air flow.
You can achieve 500 HP at the flywheel with ported stock LT! heads and the correct cam. You will need supporting mods, like larger fuel injectors and a PCM tune.
In general, unless you have extensive experience in engine building, trying to buy your own parts and giving them to an engine builder can be a big problem. The components have to be carefully matched to the final goals. Or, do you plan to assemble this engine yourself?
I would also suggest you add a "Signature".... evryone here is assuming your "black96camar" is a Z28/V8. We have no idea what trans you have. We have no idea if you have made any modifications to date. You also have to tell us if you live somewhere that emissions testing - visual, tailpipe, or PCM hookup - is required.
