Need help, advice with my 318 build

Looks almost identical to our build we did in our truck with the XE 256 H cam which made it into a super little engine. Great low end and a top end pull that suprised me.

I would suggest getting the valve stem/seat cutter 4726 and add positive locks. This gave me a clear .500" of available lift. Most 318 heads can get tight with lift close to .450" and the stem height can vary a great deal.

Hearing what your goal is and your rear gear ratio I would use the 250 if you stay with stock valve size.
