Cool! Glad to see you are making progress. I'm guessing you pick up 20 hp on these heads over the TFS. No need to guess for long though as you will be able to tell us all exactly what the difference is! Great to have some real world testing.

So, your order of business is:

1. Remove jack stands
2. Dyno
3. Order and install bigger nitrous jets
4. Order a pink majic marker to sign timeslip

haha. Had to keep it going!


20hp sounds reasonable. The 195 AFRs have some pretty impressive flow numbers.

Lot of new heads available now with some impressive flow numbers. Patriot 220cc, RHS 220cc.

I really wish AFR could compete better in regards to pricing. That's why I'm torn. You can buy a head for 900-1000 that flows the same, and save yourself $500-600..
Velocity and chamber shape slightly different, but is 5-10 horsepower worth $600 ??
