4 Barrel

I installed the cam and dual plan Perfomer at the same time. I'm not sure what all the cam specs mean.
Valve settings intake .000, exhaust .000
Lift: the same for intake & exhaust @ cam 294 @ valve 441. Advertized duration int. 276, exh. 288
Cam timing: int. opens @0 BTDC, closes @38 ABDC, lobe center 109 int. duration 218.
ex. opens @ 53 BBDC, closes @-5 ATDC, lobe center 119 ex. duration 228.
I'm also checking for a vacuum leak.

Thanks
