Need help verifying fitment for your application? Use the contact use link and included your cam details or a link to them.

Applications with over .500" lift can consider one of our many high lift spring kits listed in our store.

 

NOTE: Heads which came with rotator retainers on the exhaust will need to replace them with actual retainers. If your heads have rotators, they will need to be discarded and replaced with the same retainers as used on the intakes.

305 engines- Due to the lower spring base locations on the exhaust locations, some 305 heads with factory installed rotators will need -.070" down locks and shims to establish the correct installed heights.
