don't sweat it,the o rings will be fine

 

You haven't provided enough detail on the motor configuration for a definitive answer. What 110" kit has been installed? Are you currently running SE585 cams? What heads are you currently running? You need to focus on matching components to maximize performance rather than just throwing parts at the motor hoping it will turn out right.

 

I don't see why not. More air in, more air out = more power..... Providing everything is match as Djl mention....

So I'm starting to learn these bot on kits are not all they are cracked up to be. I think my cam has to go if I switch th TW999-6A, add the heads like I was going to anyway and a new HPi 55mm throttle body with 4.9 injectors I will end up with a way better build. Right now I'm stock heads and throttle body. My Dyno numbers came out 91HP and 111TQ seemed real low.

 

The HD site says the cam calls for a 58mm throttle body. The exhaust could be improved.

 

For the tw999-6a cam or the se pro cnc ported heads? Hpi throttle body is same price for 55 or 58 mm max flow.
