Default Intake runner size

I have a forged 6.0 with around 8.3:1 compression a tc78 turbo 80lb injectors and other supportting mods my question is would it hurt going from stock 317s that have a 210cc intake runner to a set of procomp heads that have 190cc runners reason for Askin is cause I recently melted a piston and it messed one head up and I have access to a set of procomps for cheap not sure what to do what do you guys think?

First off, how did you melt a piston?

I think I have a fueling problem I'm addressing that as well it could be a combination of a few things my motor had 10:1 compression and the best gas here is 90 so I don't know if that's what did it or if my old 60s were maxed out honestly I don't know I was spraying pure meth to help with the high compression but it's a mystery what's going on

Anyone have an opinion on intake runner size? Will a 190cc runner hurt my set up?

Well what do these procomps flow? Its pretty strange to see an aftermarket company making heads with smaller intake runners than stock LS heads.
