My report,as promised.Please keep in mind I have seen more headers then I can remember.The headers arrived yesterday,UPS,in about a week from ordering...thats good.They are exactly as pictured on the web.They are made WELL! Nice heavy tube and plates.All needed hardware and gaskets,no junk anywhere.I unboxed my new GM Votex heads(Iron),and bolted both headers to the head.The line up was perfect.If all that was correct I imagine they will fit in engine bay.All tig welds look great,and they ground off,slightly,any welds which might have interfered with exhaust flow,(on the inside of each tube).Lastly,on the header flange plate that bolts to the head there are two 1/2" holes that I do not know what they are fore,perhaps something on a non-vortec head.In my case,all is good.The holes can be seen in the website ad.

Dude,

The large holes in the flanges are for your temp sensor(s), in the head, to pass thru.
Nice to hear you got some quality stuff!!!

Mike............

Confucious say set of good headers very exhausting!!

The Chinese headers are easy to identify...they have the cone-shaped hats!

Jayare,they are polished stainless,unknown brand.I wish I could find original post that has photo.

The only thread I can find with you asking about the headers was for Summit Racing...part #g9003...I don't think these are the ones you got, tho...
                            

Installing Headers in a few easy steps.......

1. Buy headers specifying to Marty the speed shop counterguy that you need them for a 1969 CAMARO with a 350 cid engine.

2. Pull car into garage and up onto ramps. Put wheel chocks behind rear tires.

3. Open hood and realize that you shouldn't have driven 1969 CAMARO to speed shop since now the exhaust manifolds are approximately the same temperature as the surface of the sun.

4. Surf Internet for porn sites for 3 hours until engine cools.

5. Disconnect negative cable on battery.

6. Soak exhaust pipe bolts & nuts with rust penetrant and let soak while you unpack headers and gaskets.

7. Match gaskets to headers to be sure of proper fit and alignment. Use bolt holes as reference points. Trim gaskets as necessary. Place header gaskets in tray of water to cause them to swell and give better seal between header flange and cylinder head. Let soak until needed for installation.

8. Inspect header flanges for welding sl*g, burrs, and any obstructions that would cause the flange not to seat properly and completely flush against cylinder head. Grind or file as needed, going slowly and checking work progress often.

9. Check collector flanges for same possible obstructions. Trim as necessary. Notice that speed shop counterguy sold you wrong size collector gaskets.

10. Moan and curse.

11. Take wife's car to speed shop to get proper collector gaskets. Marty is on lunch break.

12. Crawl under car with 3/8" ratchet, 10" extension, and 1/2" six-sided socket.

13. Crawl out from under car cursing and retrieve 9/16" socket. Repeat as necessary until you happen upon the right combination of socket(s) & extensions or drag entire tool tray under car with you.

14. Remove first manifold pipe nut easily and congratulate yourself on soaking them with rust penetrant

15. Strip edges off of second nut because you used a 12 point socket instead of proper six-sided one.

16. Place 1/2" six sided socket onto extension and hammer it onto stripped nut. Spray some more rust penetrant onto nut for good measure.

17. Wash face and eyes to remove rust penetrant that dripped down onto your face.

18. Slowly and steadily twist stripped nut counter clockwise and give sigh of relief when it loosens.

19. Using proper six-sided socket, turn last remaining exhaust manifold nut.

20. Curse loudly as stud snaps off.

21. Go to emergency room to have rust particles removed from right eye with suction needle in delicate, terrorfying office procedure. Make mental note to remember to wear safety goggles.

22. Have right hand examined for lacerated knuckles from hand slamming into oil pan flange edge when exhaust manifold stud broke.

23. Have forehead stitched closed from gash incurred when loose exhaust pipe dropped down and landed on head when exhaust manifold stud broke.

24. Have punctures in left hand attended to from tripping over floor jack as you made your way into house with rust filled eyes and placed your hand out to catch yourself but hand landed onto rake tangs from garden rake hanging on wall where wife suggested it 'would be out of the way and no one will get hurt'.
