Curious about AAR/TA Heads

I believe it depends on how much flow you are looking for and if you have enough motor to support that higher flow with your combination. Street motors need to flow only so much to operate low rpm and low speed operation as opposed to race motors that operate at wot in high rpm conditions.
Thank you for your response.
For you I shall rephrase my question. When porting a AAR/TA head for RACING did the offset push-rod help much when porting? Just a historic question for the people who have been there. Ya know, the guy that says "back in the day" LOL
