For those people running the rotaryaviation apex seals, do you guys give it a little more clearance. I think Ito said he runs more clearance on the atkins seals because of heat expansion. Just checking before i put my motor back together.

I gave mine two thousands of an inch, the minimum clearance recommended in the Haynes manual and have had no trouble with the engine. It's a six port street ported S4 NA with 4k miles on it.
