/6 headers
As far as I can see,it looks like he does offer a product at a decent price,and it has to have performance gains.and the amount of gain is trivial,if you want a race slant you need tube headers,if you want that sound,you need dual manifolds or headers or the power pipe.mine are how they did it back in the day(old school)they are the down pipe form a chevy 305 exhaust manifold grafted onto a broken old stock slanty manifold.the only testing I have done with mine is to drop them on the concrete floor about 15 times to make sure the welds would hold.they fit all slants all years with or without power steering or a/c and i imagine if I was to make a sheet metal heat riser for the bottom of the intake it would hide the welds completely.the port configuration from the manifold pieces line up nicely and starter removal is simple.ya'll can do this,it's easy.I didn't grind the welds or clean em or paint em but will one day. Good Luck
