Cool Lq4 heads question for boost?

I have 05 Lq4 that will see about 15lbs of boost I have a set of 243's and some 317's not really sure which one to use. I prefer the 243's but dont wanna run to much compression. I'm also not sure which head gasket to run I have a set of MLS 5.7L head gaskets and a set of Ls9 head gaskets any help would be greatly appreciated thanks!

I would run the 317's with the LS9 Gasket, why are you so partial to the 243's?

Only because i payed 450 for them lol but i just picked up a 05 Lq4 from a chevy express van 3500 today for 1k with 90,000 miles. So im just pretty much trying to figure out which heads should i run thats all.

All depends on what fuel you have available.
