engine lab sucks. id go with 3d's in ybor. never heard a bad thing about their machine work from anyone, and have had nothing but good experiences with them. engine lab, those guys are morons and waaaaaaayyyyyyyyy overpriced. they installed the bronze valve guides in my ported 7m head wrong, even though the packaging was clearly marked "intake", and "exhaust". idiots mixed them up and installed some of both on each sides, so many of the ports had 2 diff length guides in them, and when i pointed it out, they wouldnt fix it. they told me have someone else do it. i will never have anything done there ever again.
