Someone school me on header size.

How do I go to battle with a well known mopar engine builder over this?

“Hey man I know you have built thousands of wallet winning engines over the year and dyno tested countless small blocks but my buddies online say to use a different set”
Well, quoting internet ding dongs no matter how true it is what they say is going to go down in flames with any “Live” person. You would have to be delicate in delivery and express not just belief but trust in persons here. Pointing out frequency of the persons in there honest no nonsense replies as well as there honesty in not just what they claim to know but there forthright been there and done it story as well as those that say up front, “I don’t know.”

With no offense to @MOPAROFFICAL, @crackedback or @69dart500 (because your still brand new here though your posts on subjects are not in question in anyway shape or form.)

All the above posters I would believe and the most to place trust in for reasons at the end of this are;

@Locomotion; as he is a drag race competitor and multi time champ so, as he says, “In my particular combo!” He writes his post. He tells you what works and what didn’t “in his particular application.”
I don’t think Myron will mind a plug right about now!

@70aarcuda AKA TONY Is also a drag racer with several cars campaigning. He shows his builds right here and as close to real time drag slips as possible. He reports the days drag strip runs from victory to part failure.
While To y doesn’t have a web site as far as I know..... lick here for his profile page and scroll down and around. Look up threads he started. There you can find his transparency in his threads.

Both guys are straight up people and offer the best out of all of us true proof of there words. Because if you look them up here at the site, they leave behind a heck of a trail of bread crumbs of no nonsense posts. Information that can be tracked down and in the books of record keeping at the tracks they race.

How’s that for proof?

My other compadres have been here for years. I can see who is smart and who is a smart ***. I give them a thumbs up all the way. Even if we don’t agree and throw spit balls at each other.
(Like siblings do! LMAO!)

Now! Lastly but not least in anything,
68dart500 is a new guy that is transparent with this awesome thread. Not knowing what would happen, he started this thread. So he is upfront and honest. Check it out;
