ARP Head Bolts

CrazyInBlack · 11-26-2007, 08:33 PM

just to make sure I want bolts not head studs right?

and they can be reused?

No Spencer.

Get the studs.

Its really a matter of preference. Studs are a pain in the ass to deal with if you have to remove the head with the engine in the car

I disagree. Actually, (on a 302/351) I prefer studs especially when removing the heads in the car.

Before pulling the head, you can remove the upper studs pretty easily with and allen-head wrench/socket and leave the short, lower bolts installed. In my experience, this actually makes the job easier for the following reasons:

1. Since the lower studs stay in, there's a lot less coolant that flows out of the block.

2. Since the lower bolts stay in, there is no need to clean off the sealing gunk that's left on the threads.

3. No need to chase block threads to clean off sealing gunk.

4. When reinstalling the head, the lower bolts help guide the head onto the block.

Sure, there are some drawbacks, but in my opinion, the pros outweigh the cons.

Guess I am just a ARP stud hater.

They cause an interference problem with my strut tower brace when removing the head.

But like I said, its a matter of preference. Most people prefer them but I think they suck to work with

Strut tower brace? You use one of those? Hell, that would make working on just about anything difficult, not just taking off the heads.

Strut tower brace=engine anti theft device

Actually you should use what the block was machined for.
In other words if the block was finish honed with a torque plate using studs on the plate, then use studs.
If the finish hone was done with a torque plate and bolts, then use the bolts.

The reason is that when the bolts are torqued into the block there will be a small amount of deformation of the finished bore. having a torque plated bolted down (instead of using studs) helps to minimize this deformation for the finished product.

If your block was not finished bore without the use of a torque plate, then that is a big mistake, if you are asking for use on an older engine, then put back what was there, unless your boosting cylinder pressures, then historically studs should help hold the down better.

yeah before the install of head studs I could remove/reinstall anything but the block without removing the STB
