For those who want strength and performance, but are still on a tight budget, we've sourced our own set of head bolts as well. Priced at a fraction of the cost of the name brand bolts, these are custom made for us by one of the largest bolt manufacturers in the USA. They feature a reduced diameter 12 point heads for easy access in applications that have countersunk head bolts (such as our Stealth aluminum heads or Edelbrock Performer RPM heads), but they also work great with factory iron heads. Rated at 170,000 PSI, they are far stronger that the factory head bolts, or even a standard type grade 8 bolt. We even include .100" thick head washers with them. One set contains enough bolts for two heads (one complete engine.) A great 100% USA made choice, strong enough for 98% of applications, at a price that won't break the bank!
Our ARP 12 point black oxide head bolts & washers sets are made from super strong 180,000 PSI bolts. That's a full 15% stronger than even grade 8 bolts. They work great for high horsepower and/or highly stressed applications with our new STEALTH aluminum cylinder heads, factory cast iron heads, Edelbrock Performer RPM aluminum heads, or any other heads that use stock length bolts.
Whenever you order bolts, don't forget a tube of ARP assembly lubricant. ARP's new "Ultra-Torque" is a special new blend of PFTE lube which ensures the correct torque will be reached on the first pull, so there is no longer any need to "cycle" the fastener (or loosen and tighten it several times), which has been the case with ARP's regular "Moly Lube" This lube is essential to get correct torque on the head, rod and main bolts, and it doesn't hurt to put it on misc other engine bolts as well. One tube is usually enough to do 4 or 5 complete engines, so it's a good investment to keep around the shop. CAN BE SHIPPED BY REGULAR GROUND ONLY TO U.S. ADDRESSES ONLY.
