lq4 heads on ls1 bottom end?
 

i have some lq4 heads i was wondering if these would be a good swap for my ls1 bottom end or if i should go another route?

Unless you are going boosted I would not recommend doing this. The 317 casting heads have a 72cc combustion chamber which would significantly drop your compression ratio. For all motor builds that is not ideal.

ok thanks for the info!
