Dasa Racing uses the latest technology in head porting as they are one of the only ATV shops in the country to port using a 5 axis CNC machine creating a perfect port job every time!

Multiple port programs available.

Head disassembly and reassembly available.

5 angle valve job available and highly recommended in most cases to ensure complete valve sealing and maximum valve flow.

Bigger valve options are available, please email or call for more info.

Dasa porting is used by many Immortal ATV team riders.

Here's how it works. Purchase the porting here then we will contact you and let you know where to send your head. You pay the shipping to Dasa, we cover the return shipping. Any unforeseen expenses found by Dasa will be relayed to you before any action is taken.
