hiya boyz, I was looking about for a machine shop that would do my 4k head. "porting the head to 30mm and maxing out the valve size."

 

I found this place, they are a cnc workshop.

 

The first head costs the most, as they have too write the programe. I was quoted 1200 for the first run and cheaper for ever one after.

 

the more they do the cheaper it gets.

If you know of any one that can do it cheaper post it up.

 

btw: they can do any head

Found some one cheaper 400 +plus parts

 

supreme heads 9274 7200.

 

This is not flow tested.

Cheap does not always equal good.

4k heads are cheap....try your own porting. get a die grinder and have a go. I used to do my k series and got good results fairly easy. let them do the vales and seat after.

 

just a thought
