Lobe sep is wider than I'd like to see and I would personally add 4 degrees more exhaust duration. It will however get the job done.

A single plane intake like the Torker 2 with a spacer or the TFS track heat are much more appropriate for the build as stated.

That dual plane intake is GOING to cost you some serious power. Trade if for an appropriate intake. :grin:

You asked what I thought and I've done that.
