max lift on stock spring

Have a '73 stock 454 with 781 heads. Is 499 too much lift for a stock spring? This is just a general question and it's in a towing application....maybe spinning up around 4,500 rpm. Thanks!

P.S. Duration is 266, if that matters.

Re: max lift on stock spring

I would NOT use them at .500" lift!!

Buy a cheap spring and retainer kit from CRANE and be done w/ it!

Just remember they sell two kit's!!!!!!!

A kit that install's at 1.88" which should be for your heads and

A kit that install's at 1.8" for the newer heads!! So beware and get the correct kit!!

Re: max lift on stock spring

Wasn't there some kind of trick to swapping them out without yanking the heads??? I do have a big air compressor. I thought you shot air into the cyl to keep the valve up, but I might be mistaken. Maybe this thread could be a dual question answering gizzy!!

P.S. will those springs work with my stock retainers, ect?
