I will get some clearances numbers together for you hopefully early next week. I also posted results from these heads & a mini stick in the dyno section last week late

Hey Jason, I've gotten conflicting answers on this one and I'm sure alot of people would like to know. Will there be any clearance problems with these heads and a F13?
