Default Holley 300-136 (LS3) knock off for boost

Has anyone used this knockoff intake for boost, wondering how the machining is, plan on one piece gaskets, not orings. Prob. more concerned about the inj. holes.

Thought I would update this, got one off Amazon for $120, came today, over all nice piece. I had to clearance it near the valve covers, there is like a rail that it hits, few minutes with a grinder and sits well. Used the FelPro
.060 gasket, checked around with a feeler gauge, compresses OK. Prob use sealer on the head side. Also bought the budget fuel rail kit, injs seem to fit the holes fine. Plan on a 90 deg. adapter, 90 mm TB.
