Im buildin a FAST car now and bought a set of the repop manifolds which are n the process of getting extrude honed out.going to hog the hell out of them as well as a intake manifold.



Which was kind of my point...
You would think someone would have made a set that was already bigger & smoother inside.
If your going to to go to the trouble of casting them, I would think it would have taken very little "extra effort" if done up front.
The guy with the ability to advertise "Flows Better than Stock" would have an an advantage over dead stock repops.

At least I think he would.

But it appears that is necessary to buy them and then "Fix" them after the fact.
Which answers the question "If they do it?"
