after losing my first head to a bad machine shop:beatentodeath: i got another head:thumb: but i left my in the old head so my question is i want to use 3mm 3g lifters but can i use my 1g roller rockers or do i have to change those also, and can i do this without having any further valve work done
 
Yes, its as easy as pulling out the original lifters and inserting the 3g ones. You don't have to change anything else. I have a set in my 4G63T engine which is patiently waiting to make its comeback.
 
when i get my new lifters in and soak them in oil to bleed them and put them in do i want to soak them in the oil i usually use or a break in oil like royal purple etc?

The ones that I have seen come already filled with a clear oil. IMO there is no need to soak them in a second type of oil. Just bleed them and install them. That's what I did with mine and they are working just fine.

Obviously, if someone is reusing a set after cleaning them then they should be primed with oil.

If you do want to do that then use whatever motor oil you are currently running.

is there a write up on how to install?
 
Go to autozone and buy a tube of assembly lube. Squirt it into the side hole until it comes out the top hole, install lifters. Voila, no draining/compressing/pumping/etc, fill with assembly lube and drop in. Huge time saver.
