Created within the Triple D confines of Barry Grant's mad laboratory, the new BG aluminum three-valve cylinder head promises improved performance and power for your small block Chevy or Vortec engine. With a greater curtain area over a conventional two-valve design, this arrangement provides smaller inlet valves and seat pressures (therefore higher revs/less inertia) typically restricted by its larger counterpart. Barry Grant claims that the heads demonstrate excellent cylinder filling with low-lift cams and will outperform when used on high performance and racing engines. Encased in aluminum, this lightweight retrofit cylinder head should entice any Bowtie diehard looking to catch the neighbor's Magnum.
