Tracy....you don't carry a back up lighter?????

 

Good for you Tracy! Although I like the 4 valve head.

 

I suspect you know more about the new model than the sales guy....

 

Not one that works at 80mph Al.

 

Although I like the idea of the 4 valve head, Tracy's response made me think. A bad thing.
The reason for the 4 valve instead of an improved 2 valve is probably because it is cheaper to do a simple 4 valve than to radically change the 2 valve head to improve flow enough to match what a simple 4 valve will produce.

 

haha....I even have a 12v backup lighter!

 

I got roped into playing Barbies. Nataly decided they were going to go swimming so stripped off all their clothes. Elsa (from Frozen) and Rapunzel shared some intimate moments while swimming when NatNat wasn't watching. I am such a horrible person. HAhaha

 

Ah! I must learn from the master!

 

Yes Greg and you can increase the combustion pressure, increase air velocity and efficiency with 4 valves. The 4 valve motors are over 230 psi. Bummer that they won't sell the head over the counter. Calling it protected property. Same with the compensator. Dealer item only.

 

I hear ya guys, but is this head really gonna flow better that the old type that has been ported and polished with a better valve setup?
