So….more header talk….this had me scratching my head

So….. sitting in the staging lanes Saturday( had a good bit of a wait before before we got pulled, talking to Vance, guy who drives the Rod Shop Dodge Dart( races it in stock).
Up walks a guy I have met several times at a get together a good friend of mine has once a year.
His name is Chris Hardy. He owns RET, racing engine technology. Tons of guys nationally run his heads in stock and super stock.
Him and his dad were hitters in 6 banger Buicks in stock forever.
Anyhow he asks how my car was running, I said OK, but better when I get around to getting bigger headers for it. He ask me a few questions. I had told him of the recent “ bigger heads and bigger intake” swap. He asked how the car 60 footed now compared to before. I told him I have enough hits now to say that it’s about 3 slower. Typical 1.47 before, now 1.50 almost every lap thus far. 10 or 12 hits thus far.
Told him I was looking at putting a 1 7/8 tube on this 418. He told me no way, he would even consider anything bigger than a 1 3/4 tube with what I have, heavy car, Yada, Yada.
He says… “ you have obviously been listening to dyno guys too much. You need to think about torque, more torque, faster down the track. You have a bigger runner head now, you have lost torque, thus the 3 loss in the 60 foot.
He said a lot of the stuff he is doing, he is telling his head customers to put 1.5 inch tubes on, not even 1 5/8. I was like..are you friggin kidding me..lol
Said he just finished a set of heads on a shoebox Nova that qualified 10th with a 327/ 275 horse motor that they installed couple days before Sonoma last weekend, and in spite of having wheelstand issues car went like 9.99..13 quicker than they had ever been…and still sorting it out.
Guy is without a doubt smart, just goes against everything I have ever though I knew about headers.
Anyhow..
