Default What would upgrading my springs and retainers only do for me?

I am thinking of just upgrading my springs and retainers on my stock heads would it allow a higher redline of 7k-8k? How much work is it really pop off the valve covers and slap them on (over simplified?). I know I will need them torqued down. If I did put better cams how much more work is that? Is there any insructions out there?

Thanks
Ralph

Anyone have instructions for swapping the heads and cams?


What can I do for $1k cams, spings, valves, retainers? If I do not have the heads ported and polished will it make that big of a diffence?

Give Trey a call. He's one of the best when it comes to head/cam combinations.

I know I am just trying to save the money. Cobbtuning at 3k is a little too much for me.

I dont know how extensive the rest of your build up is but if you are still running stock rods id be a little scared to spin them at 8,000 rpm especially at above stock horsepower.

I would do this at the same time, or at lest do this first

You are better off to build up internals before increasing the rpm's, not to mention the heat. Just a cam would help, but I have been looking for some time on these parts and have decided it is better to build up those internals first. Do the springs, and retainers with rockers when you do a port and polish if you want to go that far. Do everything in stages. Pistons, rods, rings, etc…is a good spot to start for a N/A-Then if you go turbo, no worries with something going bad if you have a good ECU onboard. Everything else will be much easier and less risk of something going grenade inside with those in place. Just another note, with that higher RPM you still might be passing your peak HP range too.
