LS5 to LS7/ZL1/L88 valve springs????
 

I have a set of stock 290s on my LS5 454.
i also have a set of valve springs that were removed from a 1970 LS7 which i believe are the same as the ZL1/L88 springs along with thelong slot rockers that I want/need to switch too in order to run a bit more camshaft.

anyone know if these are direct swaps without machining required? Or will the spring pads need to be cut?

also - setup to stock LS6 specs (using the valves that are in my 290s) what seat/open pressures do these guys provide?

Cheers

The springs should work without any modifications.

I thought that the spring pressure should match your lift. For example.....a .520 lift needs 520 lbs./inch

I would contact Comp Cams or equivalent and get their advice.
