small block engine questions

I will start building my 360 real soon and I was planning on using the mopar tube& ream kit to block oil to the lifters since I will be running a solid cam. Anyone done this procedure? Is it worth the trouble? I will be running a stock pump with a high pressure spring and stock type pan. I guess I was wondering if the lifters will have enough oil in the bores from drainback. I would like the oil system to be adequate up to 6500 rpm.
