Rob Edwards has a set.

Which are somewhere in the USPS system, on their way to Hans. I have the 85/86 blocks here, which are dimensionally identical. The only difference between the 9226 block and the 9248 block is the diameter of the holes that span the cam cap bolt sleeves- they're bigger on the 87-95 S4+ heads.






This tool set is confusing. If you buy a 9226, you get 6 pieces - two cam hold-down blocks (9226/2 times two), two cam lobe timing templates (9226/3, driver's side and 9226/4, passenger side), and two threaded rods to locate the blocks. The blocks only work on S3 (85-86) heads. If you order a 9248, you get one cam hold-down block.

So to have complete set that'll actually work on an S4, you need 9226 x1, and 9248 x 2.

The best part is, you don't really need any of them. You can just back the cam caps off one bolt at a time (splurge for a Hazet 990-8 XZN socket, trust me) with an air gun, then make them finger tight again, then go around the head and loosen each bolt 1 turn at a time until the cam is released from the head.

Or build a set out of parts from Home Depot like I did.

As Rob said you do not need them

Like Rob and Roger said, you don't need them. I did my cams without them with no problems. Slow and easy is the answer.
