Unless it’s a very stock type build, I’d suggest a little clean up in the bowls.
It’s hard to imagine they’d be any worse for a “mild performance” build than stock magnum heads.
So, if you think stock heads(or tweaked stock heads) would get you were you wanna be.......I would imagine those will as well.
Unless you can get one flowed, and have some numbers from a stock head from the same bench....... it’s all speculation as to how good or bad those are.
The EQ’s were a noticeable improvement over an OE magnum head.
