Porting an EA81t

[coronan]

Searching does not yield much for this motor let alone pictures.   So I'm going in blind.  Maybe I can get some feed back.  Or Someone Can learn from my mistakes.

 

What is this ridge about???

 

Any recommended areas to clean up?

Port is already matched to the gasket.  Actually the gasket is slightly smaller stock.

 

This head would actually be a great candidate for extrude honing,  But thats def out of the budget.

 

Questions...

 

The casting does not have too much flash.

 

Remove all of this valve shrouding?  Raise the roof?

 

 

Remove most of port divider?  Shave inside corner?

 

 

Raise the roof or just polish?

 

 

Phase 1

remove flash, Unshroud intake, blend around valve guide.  60 grit
