408 hyd roller, too much spring pressure?

Well wait, now you want to budget ****?
What do you mean "now I want to budget ****"?

Do you live in the Oval Office? We ALL have budgets! But many (if not most) of us street guys don't have the budgets for exotic valve gear that can be addressed with simpler, cheaper parts.

What if I just want to leave the heads alone and put a bigger cam in with matching springs? Why do I need to do all the things you suggest?

You talk like money's no object! And you forget not everyone lives in the USA where you manufacture parts and get things a lot cheaper than we do once it's been shipped and taxed! Not to mention the availability.

If anyone is wondering why there are so many Aussies on this forum it's because we have A-bodies too, but we don't have the luxury of OEM and after-market manufacturing like you do.
