Porting in progress...DUW??

[WRXdan]

Started porting my heads last night. I removed way more material from the exhaust side. On the intake side I just shaped because I was afraid to eat thru the walls where the spark plug tube is. I need to be some course sand paper to remove some of the groves, but overall the grinded areas are smoother than stock. I need to round out the exhaust port some more as well.

Rigth side done, left side stock.




Looks better in real life
