Thread: fitted ARP studs to my 3.9 V8 today.

On the D2 at least only the last two studs hinder removal as the head hits the firewall before clearing the studs. Might be different on different models though.

It's pretty much the same on all varients of RR, D1,D2 AFAIK.

I found it easier to just put the head on with no studs, as it sits in place on the dowels, then fit the studs.
The rear studs on an RRC fit with the head in place.

If its of interest , I was a mech for BL back in 70's , (not landrover) but we were using a computer controlled fastening tool for ali heads , that measured bolt yeild as it tightened them (air ratchet) , they had a usage counter on it as they had to pay a royalty everytime it was used , but it apparently saved them a fortune in headgasket warranty

Are we talking the same BL? maker of KV6 sold to Kia with about 100% head gasket failure rate. KV4 was similar . Not to mention RV8.

Pity they must have lost the tool somewhere.

Now the wty is cheaper than the royalty on the tool. It's sitting on the assembly line at the head fitting point but there's no one left who knows what it does.

I love the way that this place pops up high on the Google rankings if searching for info.

I've done some thinking about my current rebuild and I think I'll go for studs rather than a new set of bolts, and ARP seem to be the only company offering a kit. I have tried VPW - price good at $166, but 10 week wait (SERIOUSLY!). Called TRS, have in hand, $328 for the kit (HUH???). A set of bolts can be had for under $80. Now wondering if it's worth sniffing out a purchase on eBay ex USA for a little over AUD $200 landed.

Pressure to make a decision is off because the block has gone back to the machinists to have them redo some of their work to acceptable standards, but 10 weeks is a stretch.

Are there any other suppliers who do kits of studs? While I'm at it should I consider studs for the main caps as well?

I originally ordered mine from the USA , but they strung me along for 3-4 weeks before telling me no stock, so I manned up and paid TRS.
Maybe try Rpi in UK, probably dearer but they should have them.

Try Fabre in Lakemba Sydney. They have (had) in stock and were under $200- when I purchased.
