W2 roller rockers

sounds pretty close to my setup,except mine pulls to 7100rpm. blows through the 26inch drag radials at any rpm/speed. So more torque down low won't do much, if it can't stick.
Comp cams custom grind(roller though)
254/260 at .050, with the 1.6 T&Ds, .698 gross lift
Runs on pumpgas, limited to 33 degrees timing,running through 1-7/8 TTIs, 3 inch out. With the Super Turbo mufflers, keeps it calm and quieter while crusing.


How much porting was done to your heads?
