Valve Spring recommendation

Hopefully Ive got all this right..

I talked with my tuner and it looks like my spring in the #8 cylinder is toast, BUT its not that bad, and it looks like I will only need to replace the valve springs... I just wanted to know what kind of springs to throw in there? I plan on doing heads and a cam later on, but can't right now so I just want to put a good spring in there now so when I go to sell the heads I don't have any issues..

So which springs do you guess recommend I have installed for use with the stock cam? I don't mind spending a little more money as long as I get a good reliable spring..

Thanks

Well since you have a stock cam and especially since youre planning on getting rid of the heads later, i would just throw a stock spring back on there. If someone else was to buy your stock heads and if they put a bigger cam in at the same time, they will have to get the springs that match that particular cam they have. Save your money now and apply it towards a double row timing chain or something when you do your heads and cam package later.

For stock, I would actually go with the Comp 915's to keep the timing chain load down. You might also consider Cranes if going dual, but the 915's should be a good setup.

Hey, this is NOT a challenge, but I have not learned about this. Would you please expalin how springs minimize the timing chain load? Valve train is not my strong suit, but I want to learn.

Thanks,
Joe
