If you are indeed building an LS7 there is no budget way to do it. With 12.5 to 1 compression, a .640 lift cam and rectangular heads you'll need some stout pushrods, springs and rockers. Factory low performance stuff won't cut it.
But I digress. With flat tops you're not building an LS7, more like an L36 so the stock stuff should work.
