Cylinder head leak

[Rusty_Nail]

Just installed this high compression head and it's leaking from the corner circled. The head bolts are torqued down as much as I can get them without stripping anything out, but it still leaks after I go for a ride. What can I try to fix this? It has a copper head gasket too.

I know the head is new But... Check the head deck and cyl deck for flatness

Rub the head and cyl deck on sand paper and plate glass to ensure they're flat

Tip: mark up the sealing surfaces with a black sharpie pen
When the sharpie marks are sanded off you know it's flat

BTW head bolt torque is 12 ft lbs

Anneal copper head gasket and reuse it

If the area you have completely circled is accurate?, you might also have an exhaust gasket leak.

Ok. I'll have to wait until next weekend to mess with it, but I'll try that idea. I'm pretty sure it's not a exhaust gasket leak since I just put a new exhaust gasket on it yesterday, but not completely ruling that out either. But when I run my finger under that corner of the motor, I get enough oil on my fingertip to completely cover it. Also when I pulled the plug to check it the tip is like an ash grey color.
