16v to 8v exhaust manifold adapter kit

This kit is designed to adapt a Volvo 8v exhaust manifold to a 16v cylnder head.  It includes an adapter plate and all necessary hardware to mount the plate to the head.   Our 16v 242 currently makes 397whp using this adapter .  We feel that the stock manifold and adapter are good for over 400whp and offer manifold longevity  that only a cast manifold can offer.
