cool. Those summit pistons should be UEM/ Silvolite pistons. (KB pistons).
pay attention to the ring end gap recomendations for high perf applications based on heat volume load.
You must make the piston ring end gaps bigger. by about 40%.
EG: stock cast 350 piston ring end gap .016" Make it at least..024".
Failure to do this will pretty much guarantee piston failure when the rings butt.
(broken ring land)
The gaps in the running engine are normal, when its running. Al lot of people don't under stand this
and think the larger than typical gaps for these will create blowby and ignore the instructions, then blame the pistons
when things go bad.
