Is this a fair deal?
I think everyone agrees that Doug's and TTI's are about the best fitting headers for a small block A body. I am buying headers soon and have decided to go with the TTI's. You should be fine with either.
I'd be careful purchasing anything from KMJ Performance out of Iowa. They have a
F rating with the BBB.
I would pay the $25 more and buy them from Summit. If you would have bought them two weeks ago, you could have saved an additional 10%.
