I was also thinking about just getting a set of rebuilt stock heads because of the price, but I'm worried about having issues with cracks in the chambers around the valves and stuff.
stock magnum heads are notorius for being cracked so you'd do well staying away from them. If the heads your looking at on E-bay are truly new castings they either have to be EQ's or RHS. I have EQ's on my car and they don't have any markings on them like the ones your looking at on e-bay. All RHS heads I've seen have RHS cast onto them in big letters so you can't mis them. At 1st when I started reading I was like the others in thinking something sounded fishy if you have to send in your old ones but if they verify their new heads maybe they just want your old castings to refurb and resell?
