I had to oblong the holes on the throttle cable bracket to get mine to fit and I have the tall TFS valvecovers and TFS intake. I have TFS heads too but I don't think that will make too much of a difference. It was a must to have the 1 inch spacer and oblong the holes.

I have a set of stock heads, TFS tall valve covers, track heat intake and a 1" spacer and mine fit, BARELY. As others have said you might have to elongate the holes in the throttle cable bracket. That is where it gets tight.
