Question on port matching

Bewy said
Post 13. I have struck this with aftermarket intakes. You line the ports up on one head, & find the ports on the other head misalign by 0.100".

Agreed but I can't help but think any mismatch would cause turbulence. I am no expert, just what makes sense in my brain.

As long as the intake is smaller than the head port, it’s OK. Not great, but the reverse is really bad.
