I bought these heads used and one cylinder appears to have some porosity or possibly some damage that was repaired previously. I am wondering if this imperfection can be machined out. I have emailed Texas Speed and awaiting a reply, so I figured I would get your input. I plan on sending these in to Texas Speed for their CNC porting option.

 

It’s a non issue. But I’m sure Texas Speed could very easily weld that if it bothers you.

 

This!! If coolant was present, the chamber would be cleaner than a washed baby's *** covered in baby powder!!

 

This...

Sometime something spent a small amount of time bouncing around in that cylinder.

(I've ran WAY worse in a pinch without a problem)

 

Agreed. Easily could be welded, or run as is.

 

Thanks for everyone's input, I appreciate it.

 

No biggie and if you mill, they'll be even less... Good luck with your project...
