Guideplates, and I'd go for 7/16" ARP studs, but the hotcam doesn't really 'need' it, I just like a little overbuilding. You can use regular SBC guideplates, the pushrods (7.2") are hardened stock up until I believe 1996, I used Trick Flo 7.2" CMolly for about $86 or so.
Don't forget some springs for your .525" lift, HOTCAM springs work but they are marginal, especially if you want to rev it out a bit, they were originally for the plain old LT4, some people say they bind with the HOTCAM meaning they are very marginal.
