LS3 Manifold on 317 heads
Anyone tried this before? I heard that this combination might cause vacuum leaks cause the LS3 is meant for rectangular port heads. I was thinking if it they don't seal right try to build a thin plate adapter at the machine shop to seal the intake to the heads better.

I am planning on buying a pair of L92's but that won't be until maybe February and the engine is going in in December over the holidays. Hopefully by then I'll fine a pair of L92's for a good price earlier.
