i'm about to put my motor back together, but can't decide which set i'm going to install. i have some crane/ford 1.7 roller rockers and a set of proform 1.6 rockers. my mods are everything in my sig, and i'm installing a set of thumper heads with 1.94/1.6 valves, an afm n-412 cam, and my 24# squirter's are going back on with a matching 75mm proflow MAF. afm's site says to use 1.6's, but what do you guys think? here are the specs on my cam:
N-412 Cam Spec
Engine 302HO/351
Duration at .006 -- Int. 276 Exh. 284
Duration at .050 -- Int. 222 Exh. 230
Timing events at .050 --Int. 3/39 Exh. 51/-1
Lobe lift @ cam -- Int. .320 Exh. .320

the lift will be .544 with the 1.7's. and ptv clearance won't be an issue with my pistons.
