If cost isn't an issue would you use studs?

I have read mixed opinions, with even one person saying they didn't like using studs because they tend to leak (MKIV Block).

I think the only reason I'm leaning towards studs is the finer thread for the nut. It makes me think I'll get a more accurate torque... that and I'm somehow swayed by a perceived cool factor.

mostly stock type motor I would just use head bolts
anything with aluminum heads or making a good amount of power over 650 hp I would go with head studs

Griff

Ditto. Use some ARP thread sealer on the studs if you use them.

Thanks guys... 550hp with iron heads. Looks like I'll get the bolts and show the wife how much money I saved!!
