Mast motorsports?
I was wondering the same thing too ??
I just got a set of Inconel exhaust valves from them today for there Mast Ls7 heads. They are 2 piece and printed on plastic cover. Made in Argentina ??
I dont know how good they are I'll have to call them and see how much they can handle for twin turbo project I got OR I have to get custom set made from either Ferrea or Manley.
They probably use a variety of brands, but I have seen them use Victory (For some Ti valves) and Ferrea for sure. I'm sure they use all/most of the major brands out there though (Ferrea, Del West, Manley, Victory, Rev, etc.) Since not one company makes every size/type/matl. valve you'd need when you manufacture a wide range of heads. FYI most valves have a brand and p/n stamped on them near the tip or on the head.
v502, I'm sure they will be just fine. I'd go out on a limb and say any inconel valve will handle anything anyone on ls1tech is doing at least.

, I am sure there inconel would probably be fine but for my piece of mind I just call them tomorrow and get couple of questions answered. Thanks for the tip on p/n, I it check it out.
