I saw an advertisement on ebay for some ARP pieces, but they did not list the 4G63, so I contacted them. They responded with the fact that they could get the fasteners and for a great price! Try $83 for the head studs (part #2074203) and the rod bolts $33 (part #1076002)!! These are by far the best prices that I have seen. Here is the link, but they only show American engine pieces, you have to contact them directly.

The name of the guy I contacted is Carlos. I will be ordering soon, these prices cannot be beat from what I have found so I just thought that I would pass it on!

 

I've seen similarly good prices at http://www.lightningmotorsports.com/arp.htm
- $33 for rod bolts delivered

 

Maybe you know where I could get hold of a Cometic headgaskets and which gasket thickness they offer?

thanks
