Well I tried to call them and all I can say is they have a VERY obnoxious song playing while you are on hold. after 8 minutes of hearing it I was told by a recording to try again later. Well I ordered a set of bare heads, intake and exhaust valves, and an intake for my son in Colorado that I had sent directly here so i can port them for him. He has that 50 year old Torquer intake so I will do testing with both but honestly I really don't like the looks of the old Torquer intake. I also ordered a set of bare heads for myself that I plan on tubing, porting, and selling to raise some race car funds. Time to get my butt busy!!! This should really help out the 340 engine he bought and now I have to find a nice hydraulic cam for him.
