thorley headers

[shrtbx]

i came across some thorley headers i want to buy. Only thing is that it looks like my smog set up has only one outlet in front of the manifold on each side. I looked at some stock pics of other 86 trucks and and the stock exhaust manifold only have one smog tube coming from the front of the exhaust manifold as well The thorleys i saw have bungs coming out of each exhaust tube. Guy told me that you take your stock tubes and weld them on. Only thing is the stock ones only have that one tube . Is there something im missing? other chevies i have had had 4 air tubes never came across this before. Hopefully a few of you on here have some pics of thorleys installed. I know they are quite pricey

I would call thorley's tech line and I think the smog tubes will screw in like the stock manifolds.
