Qwik Question:- Is a brand new set of aluminum stg 3 heads from TA capable of running 10s without any work on them, if everything else is sufficient? o No:
Not a bolt-on Stg 3's are not a "bolt on". At minimum the cambers all need to be done or they wont work any better than irons. If you want to just bolt something on that has good potential in the future go with the Stg 2TE head. It has the same high-port design as the STG 3 but with the standard combustion chamber that doesn't need all the work.
