Actually the Track Heat is 1" shorter in runner length than the Street intake. I take my TFS Twisted Wedge heads to about 7500 RPM and they haven't disappointed me yet. Runner length really depends on at what RPM you planning on making your peak torque and does your camshaft match the same criteria. This is only crucial on an N/A application. On a forced induction you really don't have to worry about induction wave tuning. If I was in your shoes I would buy the TFS Track Heat and a 1" TFS heat spacer, this way you can bounce between both intakes just by adding or removing the spacer.
Just an idea
