Edelbrock E-Street vs Performer RPM Heads

Nobody is making you have the heads checked out.
Just like you don’t “have to” check any clearances when assembling a motor, or degree in your cam.

Yesterday I got a text from a builder I do a lot of work for.
He had a blown BBC on the dyno and was just giving me a dyno report.
That motor got some new Brodix Race Rite heads put on it.
They were run basically ootb(inner springs removed for cam break in).

I’m sure industry wide there is a fairly high percentage of aftermarket heads that get installed right ootb.
Sometimes that ends up successful...... and sometimes not.
