AAENS TRAIL PIPES WERE NO BETTER THAN STOCK. RACE PIPES WORKED AWSOME, BUT MUST WORK WITH FULL PORTING, .44 CARBS etc. AND NO LESS THAN 110 RACE FUEL. THOSE HEADS STOCK WERE 21 cc. SO THERE IS ALOT OF ROOM THERE FOR MILLING, BUT ITS A MUST TO CHECK SQUISH AND RUN RACE FUEL WHEN YA START CUTTING. 3:16 (yammie tony)

you must also remeber that the squish will be different if you run wiseco pistons and the heads cannot be cut as far
