The IAG Performance 1/2 Inch Head Stud Set is manufactured by ARP and is compatible with Subaru high horsepower EJ25, FA20, and FA20 DIT engines.
Due to the larger size of the head studs, a greater load can be placed on the fasteners and in turn it aids in preventing cylinder heads from lifting in race applications.
The larger size of the head studs requires the case halves to be drilled and tapped.
The cylinder heads will also require drilling to accept the larger studs.
Designed for EJ25, FA20, and FA20 Engines. Requires drilling and tapping.
Here is the list of top-rated brands that were evaluated by PM.
