I have a set of their cermanic coated cast headers on my 383. I have the Edelbrock ETEC 200 heads that have the .250" taller exhaust ports and after talking with Sanderson, port matched them with no problems. Even with the 2.5" dumps, there is more room on the sides of the motor than with Hedman Block huggers. They are SMOOTH on the inside. They have a life time warranty, I beleive, if they are not modified (the reason I talked with them before port matching). I have not fired my engine at this time so can not tell you much more other than , I'm very happy so far.
