What are the available replacement for the uber expensive Jaguar head bolts.

Land rover seems like an option, but cannot find a part number nor what Landy used the Jaguar engine like the 2000 XKR. Anyone that can help?

ARP part number?
Felpro part number?
Beck Arnley number?
Victor Reinz number?

 

Have you tried Welsh or Partsgeek? PN is NCA2650AA - Welsh has them for XK8/XKR at $11 ea while partsgeek has for $10-$16 for equivalent

Never priced them but have you looked at the Lincoln LS bolts?

 

I can tell you from first hand experience the LS bolts are identical. The Motorcraft list price is $10.28 each. If you go to a local ford dealer you will likely pay more. When i built my engine i used the Fel Pro kit from Rock auto part# ES72262 . It was $31.79 for a set of all required bolts for one head. I have not had any issues with them yet.. but they are made in China / Taiwan or some place over there. I am not sure of the quality but have yet to have any issues with them.

When i start the engine rebuild service i will be utilizing the Motorcraft units. All be it more expensive.. It is the OEM bolt in a FoMoCo box instead of a leaping kitty on it. If you would like OEM i can get them for you below MSRP but not by much.

Let me know if i can help.

 

The manual states that the bolts can be used twice, so that's an option. I reused mine.

 

Thank you guys. I will try my local Ford guy for the Ls ones.
I do know that they can be reused twice. Mine have no markings on them but i suspect they may have been off once before. I reinstalled them and had to remove them as one of the bolts showed a bit of thread in it. And sure enough it would not torque properly.
I have just finished drilling all ten holes and installing steel threaded inserts. Manufacturedr recomends not reusing the bolts as the threads may be deformed and may seize on the new threads. I will be posting a how to with pictures later.
Still curious about the Landrover part number.

 

I keep 2 boxes of FelPro ES72262 Cylinder Head Bolts in stock. I used a set on a 2001 AJ27 engine and it still runs fine after several thousand miles.

Thanks Bob. That's good to know you haven't had any issues

 

Same here- I used LS bolts- all is well.

 

While studs would be a better option arp's are not cheap. Since youre asking. Iirc i spent $400 studding the bedplate and heads on the nissan
