The increased expense is in the labor as there is just so much more cleaning, parts, and prep (multiple more hours). The head work is a little more expensive than the EJ work but you don't need to buy cams so that's good.
Now we perform our secret sauce oiling mods as part of the Pro Comp build and it doesn't add much to the cost when part of an engine build. That however still had pressure taper some above 8k RPM. The Perrin oil cooler or other is really a requirement on these engines due to how hot the oil gets. To go 9k rpm that oil accumulator is required if using the oem oil pump. We are happy to put an accumulator kit together for our clients or you can make one on your own for maybe $350.
I just think if someone will drop a big chunk on an engine build, they would benefit immensely from our failures and R&D, so you won't be getting a mystery, and then dropping $600 on an oiller cooler and $350 on an accumulator to ensure reliability is a drop in the bucket.
I just can't wipe the smile off my face blitzing this engine to 9k RPM and knowing we've made it 100% reliable to do so.

You might consider designing a system that incorporates both the cooler and accumulator. If designed well, it might reduce system pressure losses over having two separate systems. Hell, you might even include a remote mount filter using a more common and larger filter that might also reduce pressure losses.
