valve job question

[Ill give u a head start]

Ported exhaust and intake runners5 angle radius cut valve job.

which one is the better option and why?

3 angle valve job with cleaned intake runners

btw i had a last minute change. I will be ordering a IPP motor instead of rebuiling my own after talking it over with my mechanic.

The two options i mentioned above are the differences between their stage 2 and 1 longblocks.

cleaned intake runners I suppose is just deburred and casting flash removed, ported would be well...ported, they remove more material and smoothe all the surfaces to allow for higher cfm flow rate and a 3 angle valve job I believe would be on par with stock and a 5 angle removes more material allowing for more air flow at all ranges of valve opening, in general the move angles the better, the differences are very obvious on a flow bench, once in the car you likely wouldn't be able to tell the difference, on a dyno it would be obvious, higher peak, and more area under the curve
