Edelbrock, speemaster or promaxx heads

PRH said
The speedmaster and promaxx are both imported copies of the Edelbrock head.
Fundamentally, if you do the same work to all of them, they’ll make the same power.

ProMaxx purchases the heads bare and do the rest of the work right here in the USA. What exact heads they are, IDK.

For assembled heads, I have more confidence in the Edelbrock hardware.
Unless it’s a super budget deal, my preference with the import heads is to buy them bare and source my own parts.

Best move right there.
Cheapest move? IDK.

Really..... what money difference is there? Its insignificant. The trick flows can be run right out of the box. Outflow the others.

I was also able to run my Edelbrock heads OOTB, some 25+ years ago when they were a new head and everything was under a lot of scrutiny and internet reporters.

Now, not so much from what I read ......
Will trick flow maintain there high level of quality years down the road????

The flow rates are only a few cfm above the ProMaxx heads right where it counts for the OP’s cam ????? ProMaxx will also substitute a spring you spec, like for the cam your going to run, out for there’s so you get what you need right OOTB.

Just sayin.....

The small cfm spread is close to nothing. 3 cfm @ 500 Or was it higher? Dang!

To get similar performance level you arent talking much difference at all.
To me the Golden rule is always do it once, do it right.
With the trick flow heads now available, i wouldnt remotely consider anything else in a standard type head.

What’s right?
Your opinion?
The few cfm difference in the new TF head?
Im not flag waving for anybody here.
