I have machined heads from Scott Clough and one of my O-rings got damaged.  Does anyone know what size the O-rings are and where I can get some?

Just discovered it this evening.  The shop was closed and I'm waiting on a return email.  In the mean time, maybe someone here knows and after I find out it will be available for others on here.

Okay, I was able to locate the emails between Scott and I when I had the heads done in 2011!!  He listed the part as standard Parker O-ring # 2-040.  You can use viton or silicone.  I found them on Ebay for $1.71 each.

2-040/V7 - 2-7/8" X 3" X 1/16" Viton O-Ring

Maybe Mark can sticky this for a reference

NICE! Glad you figured things out. Email is great because its always on file...unless you delete them.
Do not underestimate the power of a two-stroke.
