Nrs Ceramic Seals_ Question
 

Has anyone tried the NRS Ceramic seals. If so- what did you clearance them at for an over 550 rwhp car, 3 or 3.5 thousanths?
Did you have to mill the housings to get the correct clearance??
Any other info you would like to share....like did you have any hard hot starting problems or anything else.

Thanks,
John
