Stock Merc stainless steel center rise BB&SB manifold elbows. They last forever and can be polished like a mirror. They are black and appear to be powder or ceramic coated, a good tough wire wheel bearly touches them. $100 + Ship a pair 1/3 the price of cast iron that don't last long. Another plus is they are thin walled and quite light, the exhaust outlet is 1/4 larger than the cast iron, may improve exhaust flow just a little. They are less than 1/2 the weight of cast iron and the exhaust outlet is 2-3/4 opposed to 2-1/2 for the cast iron version. You can chop off about 20lbs in weight and may see a very slight improvement in preformance. The Big Plus is you will never need to buy risers again. These are used $100+ship takes a pair less than half the price of cast iron risers. They polish up fantasticly. Bolt patern is 3-1/4 by 3-3/8 on center. They do not use the long 4+ inch studs to mount they bolt or short stud to manifolds.
