I replaced the long headers on my 70 standard 351C V4 heads with Sanderson Shorty headers. I am happy with them now and here comes the big hairy but! I received the first pair of headers, yanked my long headers and installed the shorty headers. You won't need any extension for the ram and I cut my extension since the PO welded it to the frame. I trailered my car to an exhaust shop that was recommended by my car club and he modified my original exhaust for shorty headers and out of the rack they were leaking. I figured that it was something that I installed wrong so I ordered another set of felpro manifold gaskets and tried again, and again, I believe I had at least one side of the exhaust off or another five separate times. Finally I brought it back to the muffler shop that modified the exhaust and they tried with a new set of gaskets. After not sealing up properly they pulled the headers and found that the welds were ground too close to the pipes when they were cleaning up the mounting plate and they would get hot and just blow through. After many months of frustrating exhaust leaks not to mention cash money exchanging hands with the muffler shop, I sent the headers back to Sandersons with the explanation "these are my nightmare headers". A nice lady said they would look at them and see what they could do. I was not interested in getting them back and reinstalled my long headers. and continued living my life.
After about 2 months, I remembered that they were at Sandersons and gave them another call to inquire, no one there knew anything about my headers but I was promised a follow up and got that the next day. The guy opened the box and read my note which I proceeded to explain this whole scenario. Long story short, they sent me a set of new headers ceramic coated this time free of charge and these bolted up perfectly the first time. They made good on the headers and I am happy with them now. It seems that I have to usually get the "bad part" or endure some kind of hassle in order to accomplishing simple tasks on my cars. You may have an easier time. Besides the price being high ($325.00) they are doing the job, I have lost a little bit of low end horse power but I'm not a racer anyway. Now if something scrapes under the Cat it is the frame. and that's what I did over my summer vacation! Sal
BTW those are the headers that you need. They are shaped similar to the original exhaust manifolds that came with the car.
