86onboost

ok i looking at some bare gt40p heads, they dont come with valve springs, keepers or retianers.

i dont even know if they come with vavles anywhere, if they do.


can i use stock e7te vavle springs, keepers and retainer, lifter, and rockers, on these heads, or will the performance drop down. or will it be the same as gt40p vavle springs

Stock springs suck. Get some upgraded parts, heads and cam are the worst places to cheap out on.

86onboost

are gt40p springs better than stock or are tehy the same

what part of "stock springs suck!" didnt you understand.. get some aftermarket high-lift springs, new retainers and keepers, and call it a day


dont skimp out, you will regret it

Not sure if this will work for you or not but i think it will and it will be a good upgrade for you too. the valves you can probably order through a machine shop.
