I am wondering if the 292 has any proformance parts to get a higher rpm looking to get 5000-6000 rpm if at all possible and what parts would I need to replace

Cam, lifters and valve springs.

Do you know of any websites I could order them on

For a good start, link from this site to John Mummert's site. You can likely get just about anything you need there, including informed information.

Welcome to the site.

Click the link below for an article written by one of this Forum's moderators.  This article depicts what might be done with a 292 y-block without going the route of maximum increase in cubic inches (holding to near the 292 original displacement) and not using aluminum cylinder heads, higher lift OEM rocker arms, or an aftermarket intake manifold!  The engine built is not 'all out', and would be very street-able.  Actually, the article describes the building of two 292 engines and the dyno test results of each.

Better valve springs, bigger carb, bigger cam and related parts to allow it to breathe.

What exactly do you want to achieve?  Simply picking an arbitrary rpm range may not get the performance you desire.

Balancing always helps in the rpm department.  The more the engine needs balancing, then the more the improvement that’s seen as a result.

Add this link to the one that Charlie has included up above.  This Y build uses iron heads and iron intake, but does use a set of pistons that utilize metric piston rings to make that next step improvement in the power band.

I would probably be looking around 250 at least but im not to worried about that. I just don't want the engine to over rev.  The guy I bought it from over revved it and ducked everything up

Ted, Isky cams  is right around the corner from me, once in awhile a bunch of us would be lucky and have lunch with "Isky" been many years
since those days. Gardena Ca, was and is still a hot bed for performance parts.
    In your article on the two engines, the hopped up one, does the cam have a part number, or was this something you and Isky cams  worked
out? If it's a stock number could you post it.
 Could you have gone with a higher lift?
