Rhs heads

Funny, I was just getting on to ask about them to. I want to know about the RHS LA X heads. They say you can get them with 62 cc combustion chamnbers and 179 cc intake with 67 cc exhaust, for 650.00 bucks! Add 100.00 and you get them with 2.02 valves. Are these things any good or worth a damn? Thanks
