What kind of SR5? Since you say it has 16 valves, I'm assuming it is not the 20R or 22R block.

Is it a Corolla?

You mentioned that you saw metal chips on the valves, and that is often an indication of a lack of lubrication. Besides head replacement, you should take measure oil pressure at idle and at higher RPM, drop the oil pan and clean it out, and also disassemble the oil pump to make sure it is good.

If your vehicle is 1991 model year or later, you can go to techinfo.toyota.com for online access or you can use a Haynes, Chilton, or Mitchell manual. Removing the head is definitely something you will need specifications and step-by-step instructions for.

You will need a selection of metric sockets and combination wrenches; a torque wrench, a gasket scraper, straightedge, and a special service tool to R&R the valve shims.

For parts, you will need a head gasket set that includes the head gasket, intake and exhaust gasket, etc; new head bolts, valve stem guides, camshaft bearings, and a shim collection. If you are going to take the head off, you might as well replace the timing chain/belt. Depending on the condition of the camshafts, you may need new camshafts. You will need to determine the source of the metal chips. If it is babbit material, you may need a new head.
