SB Pro Comp Aluminum Heads...For Sale on Ebay..

Drum pounding? Not at all, it was just funny about the complaining, Gees.

Heli coils are not a impossible feat, but you know as well as i do that it invites the AVERAGE guy to screw something up.

I just think its bad design and bad practice to cheap out on them in a head made of aluminum to keep cost down. They are not that much cheaper than RPM heads and more than likley they will still need the same attention as the RPM heads need OOTB, or more. I dont know I have never had a set in the shop.
