take heart get it right this time and it should outlast you.

Yes, that's the plan. I don't want to ever pull this engine down again. This is the third time I've done it in the 100,000km I've owned it.

Mate If I could get down there Id have the head and valve gear on a trailer for you and Id do you the heads.

I appreciate the offer. Why don't you live at RAAF Richmond?! :D

You've missed the most important bit of info...or are you scared the wife will see the post if you tell us how much? :D

yeah how much Ron? The way things are going (mines just hit 175k's and steams from the oil filler with an acetone smell) when mines due for a new donk probably sometime next year it will be far cheaper to buy another P38 that goes and use mine for spare parts :(

I've paid $5K so far....

The final bill will be on Monday.

When you see someone at Davis Performance, can you ask them what they think about the "head studs".

I have been told that you can get a head stud kit. So instead of using bolts, you put studs into the block and then tighten down the heads with nuts. Apparently it gives a much more even pressure and less likely to cause a leak from an overtightened/undertightened bolt.

Thats what I have been told anyway.

I had considered the ARP studs but, as PhilipA pointed out, one can't easily remove the heads without removing all the studs.

Davis' use the head bolts from earlier model V8s, i.e., non-stretch.
