Streetport Rebuild S4 Vert
Well I am not sure if I need any technical advice at this point, but I am in the middle of streetporting my S4 vert and would like to know the best cleaning process for the engine.
My engine is completely disassembled and ready to be cleaned and ported.
All services look to be in great condition and I took the motor out while the car was still in working order.
What would be some advice for a first time engine build/port job?
Any advice will help.
Thank you!

check these out:

as for the assembly itself, i hope you have already labelled everything. having things cleaned and organized is VERY helpful before you start working.
1. make sure your work area is cleaned, it doesn't need to be sterile, but heavy dust and particulates is no good for bearing surfaces and oil passages, so your area should be devoid of them.
2. lube everything first. motor oil is usually good enough.
3. take your time.

These videos will help you in the process of rebuild a 13B or 12A engine. While they deal with an older 13B from an RX-5 Cosmo, the engine internals are basically the same for any 12A or 13B. The only real difference is that on engines newer than '85, the coolant O-rings are in the irons instead of the housings as shown in this video.
The first video is engine removal. While it is an RX-5 Cosmo, an car that few will ever see let alone work on, the process will give you the general idea of an engine removal. Steps are similar for most rotary vehicles, it's the details that differ.
The next video is engine disassembly and some cleaning. This is an old carbureted 13B so the accessories bolted to the engine are different than newer engines. However the process of externally disassembling any rotary is about the same. Covered here is also flywheel removal (same for any rotary) and engine parts cleaning.
Cleaning of all engine parts continues in this video. Provided here are examples of how this is accomplished with a minimum of tools and supplies. It's a lot of labor to clean old parts until they are looking new again. At the same time, parts should be inspected.
Finally, here is the engine assembly. This video includes clearancing side seals, assembling all the seals onto the rotor, then assembling all the parts into a 13B short block.
