Advanced Induction Cylinder Head Development
Ai CNC'd Trick Flow 21deg 195cc LT1 Cylinder Head

For those looking for an option that includes a brand new set of castings with 50-54cc chambers, our 195cc 21deg head is a great option.  This 21deg head will fit most all 23deg pistons, including stock.  As a budget version of our 200cc 21deg TFS head, this 195cc variant is based on Trick Flow's 185cc 21deg Gen-X cylinder heads.  This is a fully CNC ported head, and utilizes TFS' Chrome-moly steel retainer dual spring kit, suitable for a little over .600" net valve lift.  The power potential is between our 190cc & 200cc GM LT1 ported head options.
