depends. you can use the GM ones which seem to have the easiest install. but do you want straight or splayed?...

splayed... are they the same as the SBC 350?

Here are the ones I used. I had them machine off the splayed bolts on one to use as a front cap. You will need a decent machine shop because many 4.3 blocks are way out of tolerance regarding main cap alignment.
