No problem at all.  We do it all the time.  Vertical riser insert on the Bridgeport make it easy to stand a head upright.

Cloyes makes the Ford sets....

Couple of serious sisters there - very cool.

DTS BSFC numbers are always kinda low - seems to be inherent in the software.  I tend to almost ignore the BSFC data other than a "backup" glance, and also go straight to the O2 numbers these days.  That second engine might intuitively have been hunting for a little more fuel looking at the O2 and fuel pressure numbers....but I am asuming that Blair already worked the combo for best results.

I have just left and right O2 on my dyno - but would really like to get to the point of having eight O2s - I think there is a lot to gain there in terms of cylinder variation.

Wow indeed!
I've never seen one that bad!
Wonder how the head itself brinnels?
Cast from peanut butter?

Just use the normal Meziere pump.  I ran one on the street for ten years with Fes up to around 700ish and had zero issues.  Or buy the bigger motor and impeller and stuff it into the FE Meziere housing - most appear to be the same basic piece.  I have no idea how they decided to rate an electric water pump at engine peak horsepower when the on the road temps are not dependent upon peak power in any way.  If you're running a 16v system the pump speed and water flow will go up commensurately....

The Ford Racing/Fel-Pro 1020 gasket has a flattened steel fire ring around the combustion chamber that does a better job of sealing under high pressures.  The passenger car gasket you mention will work perfectly fine in a moderate street application - something under 500HP should be no big deal.  I just like having extra insurance....

Seen ads but never felt the need to use them.  Guide liners "fix" the problem with standard valves...
