Jeff --So how much do the ARP head bolts for a RZR cost? I know they run about 550 bux for my 6.0 powerstroke depending on where you buy them.Are you talking about head studs or the thread lubricant?
This thread is about the lubricant.
Both it's a must I have never replaced a cylinder with out doing this procedure above this includes new bolts. Done my share of having engines built and ARP heads studs are in the rzr,raptor to the 6.0 ford. When I was building thr rzr I was amazed there was no ARP heads for the rzr. Come to find out me and another guy on this form where in contact with arp to get some sized up to fit the same week, worked out great.
If you listen to the guy talk the bolts/studs take a beaten just removing them. It's just save practice on a high hp. application
I recommend one not use bolts to secure the head/cylinder to the case.
Use studs instead.
As to where to source and the part number -- Read this post .. I don't know who he is -- Butt looks like he did a damn fine job ............
To answer the question at the end of the story - Yes .. One does have to machine off the Bull Nose. Chopsaw or hand grinder also works.
