Very Nice
Well like everyone else has said you do have to drop the starter out to get them in. Drivers side went in with no problems at all. I had the heads removed and thought I could squeeze them in on the passenger side but the starter was having nothing of it. I would recommend to anyone doing this to remove the inner and outer fenders if that is an option as well. Pulled the 3 bolts and they twisted right in. My only other problem was 2 days later my starter dies and I have to unbolt everything to get it out.....and the new one on.
Perfect fit for my 1977 Ford F-100
Fit perfectly, installation instructions were right on the money. Came with gaskets,bolts and adapters to fit exhaust. everything you need to install the headers. Tech support a Jegs is AWESOME very knowledgeable staff they know the product that they are selling inside and out. I look at Summit racing as well before ordering from Jegs, I am soooooooooo glad I called Jegs that are so much more helpful and courteous than Summit.
Not bad
Pain to install but the product was good, quality material, still sounds good even though I had to massage one of the pipes with a hammer.
