M113k Ported Heads
Letting them go for $3500 shipped.


BTW - stock heads flow about 260 cfm intake and 160 cfm exhaust. These flowed 295 intake and 194 exhaust. A ~13% gain in flow on intake and a ~21% gain on exhaust.

In short:
ExoticMetal (Brooke)/Shardul is who I purchased them from. The person that did them is very reputable in the industry but I have been asked not to share it. They may pop into the thread and discuss.
I didn't install them but there are a number of members on the board that have them. More so than any other ported head.
