AI or Comp can help pick a cam. Any idea who ported the heads? The larger bore can afford larger valves, but you want to be careful not to go too big on the runner size. TFS 21-degree heads out of the box or the AFR 180 & 195cc are great choices for a 355 seeing mostly street duty as are ported LT1 heads. LT4 heads tend to be too large.

trick flow will be much better than LT1 heads get them cnc ported. your engin is a big air pump . so free cold air intakes good manifolds large throttle bodies. good heads withporting and long tube headers good exhaust go hand in hand. the better it breathes the more you will get out of it. putting nos on a bad breather is a waste.

you guys are not paying attension!!!  she asked if trick flow heads would enhance her proformance. the anser is yes!! they will out flow the lt4 heads. but she needs good headers and intake to do much good. without good air flow you will never get to the 10's.
