Interesting, I ran the tfs-r with no spacer. I thought I still had the tall covers at that point, but maybe I'd changed to the fox body covers already by then.
Well I just measured both sets and they are nearly identical on each side. The ones that don’t fit rise in the middle. Not sure what the conflict was. It’s been years since I tried it. .. any way not sure what tall is but they are 3.75” inboard and 4.25” outboard hight.
I ran a 1inch no hole alum spacer on mine to clear the tall V/Cs. Came from Cutting edge design back many yrs ago. Also had a nice egr block off he made.
I've been pretty busy and posting the pics took a back seat this week. It's not good, which is in line with my luck. So you know the "3rd engine in 50 miles" in my profile? Well.... I don't think #3 actually happened, I paid for #3 but the work was never done. It has the same damage I remember being there when it ate itself years ago!
Lets address the elephant in the room, err engine...
#8 clinder is pretty badly damaged. From what? Who knows. About 10 years ago I had my GT40 intakes powdercaoted and they did a bad job of sealing the intake before blasting. "Sand" got into the engine and caused damage so I pulled the engine and took it to be fixed. The machine shop was supposed sleeve the bad cylinder and clean up the others. These feel pretty deep, you can stick your fingernail into them.
After seeing this nice little surprise I think I paid for a lot of work that was never done. Additioanlly, I dont believe they assembled the long block properly. How does an engine with almost no miles have this amount of damage?
Here are my Canfield heads. They have good sized ports, large valves. I will probably have a 3 angle valve job, new springs and seals put in to match the new custom cam (whatever that specs out to) to be safe
Notice how the wrong size gasket was used. It booked nearly .25" of each port

Could oil or gas have leaked from the plug hole? Or more likely something ran down, pooled and then down past the spark plug area?
