Quick SB header questions
« on: July 20, 2009 - 07:47:56 PM »
 :working:
I am cranking along on installing some old skool Cyclone headers on my SB 360 motor in my 73 challenger. I made the simple mistake of not installing the headers on the motor before I dropped the car on it. No biggie, right.. :dunno: :roflsmiley:
so I pulled the steering box off the k frame, and put the drivers header in from below, then reinstalled the header. There was a little wrestling, but not too much cursing.

I kept the studs and nuts, so I know I don't need to peel them out. 
so I managed to get the drivers side header on my engine with the gasket.
I used some NOS bolts and conical washers from my exhaust manifolds.

Q. 1 Do I need to use the conical washers, or do I need to use a flat washer & split washer instead?
 
The second to last bolt could not accept a conical washer, so I used a short bolt w/integral washer that worked. It seems to have plenty of thread grab, so I assume Its all good.

Q.2 am I supposed to use sealant around the gasket & bolts? I am not familiar with good standard of practice on this stuff, so pointers help.

 
The passenger side seems just about the same, the only question I have is do I need a new transmission dipstick tube?
Thank for the input!

I just use studs or bolts with a washer.  You might need sealant on the threads if the odd one goes into a water jacket.

The four end header bolts will need a sealer on them as they go into water jackets. I would also recommend using I believe it is the Permatex ultra copper on the header gaskets to help them seal to the heads.

Use the expensive copper brand gaskets; I just had to replace my cheap paper ones.   :villagers:
