There is an old thread for this question, but thought I should start a new one in case any new solutions are available.

I have a 66 Hardtop. Converted from 230 L6 to mid-70's 350 small block. Engine bay is stock.

Having difficulty with exhaust manifold/header clearance from shock towers.

Tried shorty headers - fit passenger, but rubbed driver. Tried rams horn manifolds - fit driver, but rubbed passenger. Both of these matched fitment on the websites. (GM Classic and Summit Racing)

Purchased - supposed 67 Nova V8 exhaust manifolds from Ebay vendor. Same as rams horn - fit driver, rub passenger.

I'm no mechanic, so posting this looking for "purchaseable" solution.

Thank you!

I have a 67 SS with the stock front end. The engine is a 383 stroker and I use Doug's Headers, part#D367Y and they fit perfectly. They are a mid length, 1-5/8" diameter, 2-1/2" collectors, Ceramic coated header. You can also get them non coated.
