PowerFlow Plus Manifold and 85° Riser Kit Polished
IMCO's innovative patented cast aluminum manifolds and risers are designed with internal runners for 510 cubic inch, naturally aspirated, or blown big block Chevy engines. Fully water-jacketed with 2 1/4" primaries, they are equal to any tubular header on the market today. Dyno results have proven that PowerFlow Plus out performs headers in torque, rpm, horsepower, and most of all longevity. All stainless steel tail pies are custom made to your exact specifications. We off several internal mufflers for you to choose.
