I'm running very simalar and used std "new" head bolds. Not hada problem yet, done 18k miles so far

simbo

Off the top of my head I think they are £120 a set.
I would use new ones.

I re-used them once already when I did the head gasket on the old 2 litre.
I decided it wasn't worth the risk on a new build. I also fitted a new oil cooler donut, oil and water pumps along with a few other bits

o the arp ones was £130 might be better to get them.
got a new oil pump ordered

cheers david

I'd use the ARP ones (standard size), can be bought in the states for good money.

Go for the ARP studs, They are a better bet than even new standard ones and will take a lot more abuse, should you go for more power in the future.

IN MY OPINION

Standard ones are good for 500hp for prolonged time.

So are sti valves but we wont go there...

Theres more 500hp cars running arp than there are running oem bolts.

IMHO.
