HI Eddie
Congrats on the new best, i was wondering yesterday if you'd ran the car since the head upgrade.
How did your 60fts compare to last time out. I wouldn't have thought that amount would make much diffence, unless you had the lash way too tight.
I run my .590 at .022 all round cold lash.
Did you do a plug check or try jetting the car up for the cooler air.
Post the incrementals of one of your tickets up.
