No more having to mix and match fasteners for various block and head combos - the unique stud design fits all of them. Any combination of D15 or D16 block or head, non-VTEC or VTEC, D16Z6 or D16Y8 heads or blocks, etc.
The SpeedFactory Racing 4140 Head Stud Kit is great for most forced induction applications up to 600+HP and includes oversized forged nuts & washers for superior load distribution.
