I don't see a fitting for the heater hose.
Is it drilled and tapped for the bypass hose nipple?
I am wondering if this is the version machined for stock heads, or for W5 heads which cannot be used with stock style heads.
That intake style. There all made with the threaded bypass hose.
The M1 for a standard head can be made to work with a W5 and visaversa. I have both intakes. It’s just a attaching screw point adjustment. A dremal can handle the issue.
