The guy might be a scammer, or at least a very rude and childish person.

I asked about some info on the ETEC 200 heads and Scoggin Dickey TPI intake he is selling for $800 or BO, and not only does he not seem to understand when someone asks him a question, he gets very rude and offensive when I said I don't want them.

Then he starts emailing me that I don't know what vortec heads are (I didnt' even mention vortec heads, but in his world maybe I have) and then trying to act tough and saying he BETS his head and intake outflow what I am running (After I told him I am not interested as the SD TPI would flow less than my Lingenfelter ported Hi-Flow lower intake manifold).

Just for FYI beware , as he might be a scammer or a stupid little kid.
