if i don't have to pull the heads i won't. i'll try the light springs first. if i had more than enough clearance like that then i should be ok for side clearance. they are not hugely domed. i just don't want to play patty cake with my valves. if i have clearance issues then i will pull heads and try both your paste way and the caly as well. i'm sorry but i'm new at this part of clearancing and have never had to worry about it before
thank you for bearing with me and helping
