Just purchased a set of ARP head bolts for about $442.00, is this about the going price for these suckers? There is some machining to be done as well, correct?

That price is about right. For a proper install the rocker pedestals need to get machined to allow room for the hardened washer and nut.

Ok, will do that when I get my new rocker arm stands. These diesels aren't for the faint of heart as far as the pocket book goes, that's for sure.

Since I have this torn down, might as well do some upgrades. i have a question about injectors (like this hasn't been covered right?). Didnt find quite the answer I was looking for though. Since my engine was originally non-inter-cooled, but I have an intercooler now, is there a difference in the injectors besides being 9mm for 1st gen, or 7mm on the 2nd gens? Can I run 7mm injectors with sleeve on mine, or would it just be better to get a 2nd gen 12 valve head with 7mm injector ports? Any other input would be great also if there's a different way to go. Thanks!

If I'm wrong on any of me info... please correct me.

It sounds like you are looking to make more than stock power... Non-ic heads are prone to cracking because of the bigger bore. I *think* the sleeve option is for better selection of nozzles, not necessarily less chance of cracking. Pop pressure is different regardless be between VE an P7100.

Would like a little more than stock. Just pulled head off tonight...



Definitely leaking.... I would really like to get ic head...maybe will see what price difference is before taking to machine shop.

Just so you know, the 9MM/7MM thing is from NI to Intercooled, not first gen to second. So anything later than 91.5 will be good to go.

Gotcha...please excuse the improper terminology.
