Cleaning up the head questions/ slight port / polish

[Bloodlust182]

I am going to be working over my TT heads for my engine that will replace the N/a one in my car right now. Upon inspecting them I did a quick test of pouring water into the combustion chamber bowls and the intake valves on Cyl 1 leaked water out. I thought the valves were bent but I took them out ,cleaned them, cleaned the valve seats up, re-inserted the valves, and did the water test again. The result? they did not leak. Could carbon/debris have held the valve open enough for water to weep out?

Now as for porting/ polishing the heads I have read some very long threads on the other site and i have drawn some conclusions about porting/ polishing them. My main goal is to really just get rid of the casting lines/flaws and remove any rough edges that are in the intake side then open up the exhaust side slightly.

Here is my list of Do's and Dont's I have made so far. Correct me if I am mistaken in my ways.
1. Port match the intake gasket
2. Do not take much material off the "eyebrows" in the intake port.
3. Knife edge the intake/exhaust port divider
4. Remove the ridge that is above the valve seat.
5. pass over the intake with 40/60 grit and no higher to promote fuel atomization.
6. Polish the shit out of the exhaust ports.
7.smooth out casting lines on sides of ports.


I have all the time in the world and don't mind spending 40+ hours working on these heads. I don't want to hear any "just take it to a shop" answers.
