Question about valve seals and lift / LS7 heads. Hello everyone,
I'm running GM LS7 cylinder heads, I'm wondering if the stock GM valve seals have enough clearance to run up to 700 lift. I'm running PSI1511 springs with the Katech retainers that put them at a install height of 1.85, springs bind at 1.10. If not the GM seals, what seals would you recommend I run?
Currently my cam is a 242/256 .646/.668 lift. No spring pocket work has been done, straight stock LS7 heads, stock ti/sodium valves. I'm getting my heads cleaned up locally and would just like to know what type seals to replace the ones in it now as I do not know which ones are currently on the heads.
Thank you very much,
Adrian
