Head Bolts Or Head Studs

[MRHD66]

Just wondering what are better and what people have used head bolts or head studs and what company you get them from

ARP.

Depending on how far you’re going with it, studs will have a stronger clamp than the bolts

/\ ARP , I’d just do the studs if I was going in there

The arp studs provide better clamping then the bolts but that being said it wont be an issue running standard bolts for most peoples cases. When I did my head I used standard bolts and with 315kw no problems with them.

I just installed ARP L19 studs in my VQ as the standard rod bolts have a bad habit of stretching under power and lifting the head at around 500hp. The extra tension on these should help over the standard ARP's.

Bolts actually twist when you tension them down, and in my case they can damage the alloy thread as you tighten them, studs with arp lube are a much better idea.

I Was thinking ARP Stud kits for my RB25/30 as I'm hunting for 350-400rwkws

Standard Nissan head bolts are very cheap from Nissan But with the power you're chasing you're probably better off going with a set of ARP studs. They can handle a bit more and are also reusable.
