ARP SVO/Fontana alum block, w/94up Yates hds, hex Head Stud Kit

Starting with a 12-point alloy steel stud, this kit is built for serious performance. ARP's hex head stud kit is designed specifically for SVO/Fontana aluminum blocks that are paired with 1994 and later Yates cylinder heads. These studs are a critical component for ensuring a reliable seal between your block and heads, especially when you're pushing your engine hard.

The hex head design on these studs makes installation and removal much simpler compared to traditional nuts and washers, especially in tight engine bays. This can save you time and frustration during assembly or any future maintenance. ARP uses high-strength alloy steel for these studs, which offers a good balance of strength and durability needed to handle the clamping forces involved in performance engine builds.

When you're rebuilding the top end of your engine, especially with performance heads like Yates, using a well-made stud kit like this from ARP is a smart move. It helps maintain consistent clamping pressure across the cylinder head deck, which is essential for preventing leaks and ensuring optimal engine performance.
