Im ready to purchase headers for my 68 B body 75% street 25% drag machine, its a 505 in with stealth heads. Im thinking 2" primaries. Is there a best fit best peformance header you guys use. Im going to use 3" pipe to the back bumper.
I can say for fact that there isnt a perfect shelf
header for your engine but if you buy a shelf header
you should add collector extensions so you end up
with about 16" from the end of the primaries... 2"
is pretty close... but a 1 7/8 will give you a better
low end torque but you will loose some upper power

Mine were coated when I bought them and it still looks good 3 years later.I know you can buy them bare so you can get them coated yourself. Gus

Well I bit the bullet and ordered the Dougs 452's, is that a coated finish the pics show or are the bare steel?
I would advise that you still put collector extensions
on them to get about 16" total... that will give you
more torque.. the stock collector is way to short on
any shelf header(its a cost thing)... also what diameter
is the collector... you should have 4" minimum
