Good engine builder in South Jersey

I have a 68 dart gt with a 360 , mild voodoo cam (256/262,454/475 lift), 9.5to 1,performer intake, Edelbrock 4 bbl, repro manifolds and Chrysler electronic orange box. I just bought it this way, and it is mild, too mild for what I wanted. I would like to upgrade the cam, and maybe have the heads next. My question is, who is in the area that has a good reputation with small block mopars? The last thing I want is problems from a jack of all brands engine builder.
