Header x tensions ?
I am looking at HEDMAN header extensions for a 90" = need 1 o2 sensor
What did you guys buy, because I only see them offered in either both or none.
1.buy with both, and cap the right side?
2.buy with out and put one on?
3.do they sell the one I need and missed it?
Thanks

New headman headers should come with the collector reducers/adapters so all you will need is what is called an 02 bung & weld it to the left side reducer. Summit has them -- 11.00.
If you do not have the reducers you can go either way with the extensions. With or without the 02 bungs.
I called Jegs two weeks ago, Headman does not make a Y pipe for our 90's, it will need to be fabricated.
Suggest a 3 wire heated 02 sensor.
Disclaimer:
I have zero hands on header experience on this Vette however I have built a # of custom long tube header sets. including 2 stainless steel sets for street rods. My Vette is a driver, the plan is for Headmans, fab the Y pipe. Heated 02 in the reducer, high flo main cat & the jury is still out on what mufflers to use. At this point I am considering resonators only from the folks that make power sticks.
Hope this helps.

This is what I am looking at from summit. I need to know if it is easier to use the reducer with o2 bung(will it reach?)
Or use the weld on bung?
Hedman Hedders 68440 - Hedman Street Hedders
Hedman Hedders 18809 - Hedman Universal Header X-Tensions
these are the options they gave me for o2 sensors.
Hedman Hedders 15205 - Hedman Weld-In O2 Sensor Bungs
Hedman Hedders 21117 - Hedman Oxygen Sensor Reducers
