Alf Posted February 10, 2005 Share Posted February 10, 2005 Yes that's right ARP don't do rb25 head bolts, not even head studs. If you want to upgrade, ARP rb26 head studs are the way to go, the block will need redrilling for the thicker studs.

maximajim Posted May 25, 2005 Share Posted May 25, 2005 Measure it yourself, ARP's website have a form you can fill out and they will send you a custom set.

B33st Posted June 7, 2005 Share Posted June 7, 2005 Any one know the differences in size between the standard rb25 head bolts and the ARP rb26 head studs. My head and block are at the machine shop at the moment and they just want to make sure there is going to be a big enough difference in size to re tap the block properley. leigh.
