i read about this company, and called the owner, he seemed really nice and advised that the package (heads, intake manifold and roller rockers) was worth about 525 hp on the 496 HO (with stock manifolds). Ray (the owner) further davised that the package would run for about $5k (much for for your money than the AZS&M kit) and the heads saved about 110lbs in the process.
any comments on the company? has anyone done this yet???
