Slant 6 Turbo 68Dart Project

What do you want to know? Weather they accomplish their task or not? I'll be able to tell in time. One thing I am happy about is the head was INCREDIBLY EASY to pop back on the block with them. It will make a nice addition if the head has to come off and on in the car. It's lined up and done. You also get to torque them to 85'lbs instead of 65'lbs. No head bolt stretch like i experienced on the last engine either. I had to put washers on the old head bolts in order to get it to tighten down again.

The ARP studs in my engine are studs that were bought as a"group-buy" a few years back. The "off-the-shelf" ARP studs from ARP for the slant six are, for sure, an upgrade over the stock, OEM head bolts, but the ARP "off-the-shelf" items are machined from 180,000 psi stock. The "special order, group-buy" ones we ordered were 220,000 psi. ARP had yet, another set available that were 260,000 psi, but we didn't opt for those (overkill/too expensive.)

Recently, I did some investagating and was told by Summit that the ARP studs they sell, were 220.000 psi.

Several phone calls to Summit and ARP unearthed dditional information that revealed that the studs were, in fact, 180,000 psi and that the 220,000 number was wrong.

I just wonder which set of studs you ended up with, in view of the infornation I finally discovered.

Because our group-buy was necessary for us to obtain studs made from the 220,000 stock, I thought you might want to make an effort to find out which strength you really have. It turned out that the Summit information was wrong... and that can happen.

I don't know that it really matters; they will all work, I am sure...

But, it would be nice to know....

That's why I asked. :glasses7:
