LOL. I agree. Great point. LOL

Chamfered both sides of the washers (they’re flat unlike the head bolt style washers with the generous factory chamfer) for the head studs and started roughing up the head surface side. The chamfer relieves the sharp edge which allows the fat surface of the nut to more fully engage/spread the load on the washer. The roughing up on the head surface side keeps the washer from spinning and acting like a bearing which should make for more accurate torque.

Since I’m using the 1” blower spacer I needed longer bolts. Well on one part of the case I couldn’t fit the longer bolt because of the drive gear overhang. So I ordered some double ended studs along with these nice 12pt stainless nuts. Some other trick pieces I have coming are some A4 stainless spherical washers to match the flat hex head conical seat bolts I replaced with studs. ARP is super proud of these too

I seriously doubt that those are actually 10.9 grade. The ARP stainless hardware is only a little stronger than 8 grade. That said, I'm sure they are perfectly adequate for what you want to use them.

This was my first attempt, at my concept, of removable inserts for the spacers. I plan on them being secured to the spacers. I believe I should’ve waited longer for the epoxy to cure before pulling them. No biggie ya live, learn, and adapt. I do think it’s going to work though and the inserts/epoxy will stay put. Ill be able to see if they do actually do anything with some dyno visits. I made them extra thick so I could shape them with my porting stuff.

My redneck flow bench has shown me a few things....I’m able to increase the velocity pressure and total pressure using a convergent pressure recovery plate. The flow speeds go from 220mph to 270-300 at 2000cfm though the 4.5” intake tube down to the 4” TB. The increase in mass flow from the system is considerable. I have some more testing to do with vortex generators and turbulator strips/tape. I have some ideas for using them within the lower manifold, intake tube, S/C Inlet, etc. It’s basically a tunnel ram intake I’ve developed with the use of the spacers and epoxy for the floor. My intent is to gain and maintain airspeed post intercooler. (The manufacturer design makes for extra turbulence/heat to be added along with massively decreased airspeed.) I hope for better cylinder fill and fuel shear with the increased speed. I’ve also been tinkering around with using the AN hose inner support springs as “turbulators” within the intercooler hoses. The hoses are insulated from hot engine bay heat with Heatshield Thermal Sleeving so they don’t gain radiate heat. The “turbulators” increase the heat transfer within the system. I also redesigned the inlet/outlets for the reservoir so as not to introduce any air bubbles into the system. (Air = less thermal efficiency) . I’m also on another boron nitride kick....powder .5micron along with brushable and aerosol. This stuff ROCKS! Thermal conductivity, Low friction, low rates of wear, non wettable...All sorts of good stuff coming....
