Shoot me a pm $ on just the chambers only,
Mine is going to be more turbo street than all out race... And beside NRE gets 1500hp out of heads that flow about 300 cfm when boosted & I'm not sure if efi engines suffer from large ports on the street like a carb'ed engine @ low rpms.I usually go for the overkill side of everything ( And usually wind up with a mess)God they look sweet though
