This is the style that came with my Ventura I have used Hedman, and used to sell them They always fit nice... mine have the ball type collector, which seems to work well. They are round tube and require round gaskets....I have recently changed the second set of gaskets. My big car has 18 year old cheapie steel street headers, and never leak and look new...
68168 - Hedman Hedders Elite Headers
Elite hedders can take the abuse where others fail.
Hedman Elite Hedders are made with ultra heavy 14 gauge aluminized tubing and utilize a bulletproof 3/8'' flange. A thermal coating is added to resist the intense heat and adverse elements common to engine compartments. Hedman Elite Hedders also come with a Ball-Socket style collector. Elite hedders can take the pounding and vibration of any off-road conditions, extreme hard use and can deal with the heat build-up found on motorhomes and towing situations.
And if you buy from Mopac...I can pick them up for you or Chad can. That is if you are not in a hurry and will wait until I show up in the spring. Free shipping if you wait.
