Heads
I am looking to get a set of heads for my camaro. I have a Carbuerator 350 4-bolt engine. Question is, which is better Angled plug heads or Straight plug heads. And what would be a good head to use?

Depends upon what else you've done and what you want to do with it.
For stock type replacements with a performance improvement, the World S/R Torquers are an excellent choice and for a decent price. Their Sportsman II's would be the next step up.
AFR, Twisted Wedge, Edelbrock, Holley are also all good choices, the deciding factor being whether or not you need all they offer and if you're willing to pay the price to get them.
As for straight or angled plugs, about the only advantage angle plug heads offer is header clearance. they were originally conceived thinking they would offer better flame travel and therefore better performance; further developement has shown spark plug proximity to the exhaust valve is the real factor.
