..and think I found a small way to improve it...
Got it today and looks like a great product and look forward to getting it installed to see if it can mitigate IM heat soak issues further. I still need to order the additional gaskets before I can install it.
When I mocked it up and placed the hardware in the holes so I can see if I would need to do any port matching, I found it suffered from the same issue as the BBK throttle body. Not the fault of the spacer, but more the fault of the IM. The bolts holes are just too large for the hardware and allow for a lot of play. This would make any attempt at port matching it futile as it would be difficult to place properly when installing it. So...just as with the BBK, I used the same logic here. and it worked perfect...
Spacer with gaskets installed:
Thickness of spacer for those curious:
Dowels created for improvement:
5/16" OD, 0.035" wall thickness, 304 stainless tubing, cut to about 0.8" length (can't be any longer than 0.9")
Picked any 2 holes far apart from each other and drilled with 5/16" drill bit:
Drilled matching holes in spacer, same 5/16" drill bit:
Dowels installed into spacer:
Perfect tight fit onto IM:
Will need minimal port matching, mostly just a little of the spacer needs to be matched to the ports, but Steve did a great job of getting it super close.
There ya go. I can probably drill the bolt hole very slightly using the same 5/16" drill bit for the match holes in the heads and push those dowels through the spacer slightly. That would get this setup 100% dead-nuts tight and centered from head to spacer to IM...
