Tim's Valve Spring Tool Now Available
1) Thinner stud on LS1
2) Angle, which contributes to the bolt breaking
Right ?
The other tool has a curve which is drawn down the side of the rocker rail as the spring is compressed. To compound the problem, a rocker bolt is normally used with that tool instead of a heat treated stud, which stresses the limited number of engaged threads too much. The angle of that tool forces the bolt toward the spring and can easily damage threads or break the bolt/stud.
As Shon pointed out, my design has no curve so the compressing force is longitudinal on the stud. The stud also has full thread engagement to eliminate the possibility of damaging threads.
Tim's tool is far superior in design and it would be virtually impossible to break the stud or damage the head during normal use.

I've started my cam swap yesterday, and today I just swapped my springs for new Patriot Golds.
Tim's tool worked like a charm. Spring compressed enough to lock the new keepers, and made the "spring/retainer" assembly centered around the valve stem very nicely. Oh - and I used the TDC method to keep the valves up.
Again, the best thing about Tim's tool, is that you have a lot of clearance, even under the cowl. I had no problem with the rear ones at all.
I highly recommend this tool.
Here's a couple pics from today:
The Best V8 Stories One Small Block at Time
Advantage:
You can change two springs at once, saving a little time.
Disadvantages:
(1) It costs several times as much.
(2) It is taller and therefore more difficult to use in the confined space on the rear of the engine.
(3) It creates a sideways twisting force on the two bolts that mount the tool to the head, creating the potential for thread damage to the rocker pedestals.
I've got it and love it.... and its not too tall... in fact the under cowl springs are easy.... its just trying to put the damn locks back on is whats hard

My design is flat with no raised areas to have to work around!

ah yes....
yours would be handy for the back ones... thats why we need BOTH
As a side note. The average person can do all 16 springs in 1.5 hours with my tool, and my tool is $ 70 dollars cheaper then the others on the market.
I will out of town for 2 weeks starting July 29. If anyone wants a tool please buy them now since my last day to ship will be this Thursday afternoon until I get back around the 11th of August.
