I'm no expert but I've been told the intake needs to be rough and the exhaust can be smooth almost to the point of polished. Also been told if you remove anything on the exhaust side to take it off the roof of the port. You can also remove material from the short side radius of the port. But without having a flow bench it's probably not worth the effort.

I would match the port to the intake boot while you are that far Ino it. I would do valve seals too.

The intake ports and insulators are a perfect match from factory.

Im cleaning - lapping - new seals on valves as soon as my NEW spring compressor arrives.

A "buddy" borrowed my old NEW spring compressor and thats the end of that!!!

Not messing w exhaust ports.

A slightly rough surface will flow better than a perfectly smooth surface. (Think golf ball)
A polished surface will prevent carbon deposits.

Yep. No need to mess with the ports. Just cleaning up the casting flaws and making the ports a uniform texture will help.

There is a whole world of port tuning if you want to go that way.
My suggestion was more of a "while you're there" improvement over stock. Like the grease nipples before.

Keep up the great work mate.
I'm not sure, but don't ask Brodie.

Way to many build and half done projects to list here.

I would love to be rich enough to buy a flow bench and just start trying stuff on old "junk" heads to see what works and what doesn't.

I had never heard one was in the plans.
