DESCRIPTION: The 5770 valve spring seat/locator kit is intended for applications requiring the use of hardened valve  
spring seat/locators for Edelbrock Big Block Chevy and 460 Ford Performer RPM and Performer cylinder heads. The  
5770 kit is designed for use with the #5745 valve springs that are standard in complete cylinder heads # 6045, 6047,  
6049, 6055, 6066, and 6067. The spring seat/locator has a register for the I.D. of the inner spring that has a .795” dia.  
and the seat O.D. is 1.52”. The spring seat thickness is .060”.  
INSTALLATION INSTRUCTIONS  
1) Remove valve covers and rocker arms.  
2) Remove the valve springs. The removal of the valve springs and the installation of the spring seats should be done  
on one cylinder at a time with the piston at Top Dead Center to prevent the valves from falling into the cylinder with  
the valve springs removed. A proper valve spring compressor is required to remove and reinstall the valve springs.  
3) Remove the valve stem seals. Be careful to not cut the sealing surface of the seal when sliding it over the valve  
lock groove on the valve stem. If the valve stem seals are soft and in good condition and are removed without  
being damaged, they may be reinstalled. If the seals are not in good condition or are damaged during removal,  
they should be replaced.  
4) Remove the .060” shim from the valve spring shim stack. To maintain the same valve spring installed height, the  
spring seat should replace a .060” shim from beneath the valve spring. There may be only one .060” shim under  
the valve spring or there may be a .060” shim plus some other shims needed to set the valve spring installed  
height. If there are remaining shims after the .060” shim is removed, the remaining shims will be installed  
underneath the valve spring seat.  
5) Install the valve spring seat/locator. Any shims left after the .060” shim is removed should be installed underneath  
the valve spring seat  
6) Install the valve seal. The valve seal should be lubricated with a small amount of engine oil when it is installed on  
the valve stem.  
7) Install the valve springs.  
8) Once the spring seats and valve springs have been installed on all the cylinders, install the rocker arms and valve  
covers.
