Highest flowing sbm heads?

You are talking right straight out of your *** if you think flow is everything. It’s not even close that its NOT everything.

Do you actually port and flow cylinder heads and build engine? And I don’t mean bolt them together?

Asking for a friend.

If you would just take a minute and read the whole thing and other things I stated, instead of flying off the handle and looking like an ***, you would find out that is not what I meant.

I think Mderoy has some IMM prepped rhs heads. They are 270cfm head. Not available anymore but a nice flowing budget steel head.
I think IMM might’ve had a cnc program for the intake port that got them to 290cfm.

Anyways, not really a head to spend much time on in a thread about “highest flowing SBM heads”.

That was a great head that every small block should have gotten, cheap and made good power. It's a shame they don't make them anymore.

I figured you would have some valuable input on the W series heads.

Nope, he is too busy getting hurt feelings from the new guy disagreeing with his internet friends.
