360 head trip

what valve angles would you suggest for for a .500 lift cam after lash? at this point would you gain much with a 2.02 valve and bigger bowl over the 1.88? i wonder about the bigger valve shrouding and and slowing air speeds. not an expert by no means just wondering thanks.
here are the latest numbers
.100---55.3
.200---111
.300---176
.350---198
.400---213
.450---224
.500---235.3
.550---240.7
.600---243.2




At this point it's gonna take a good valve job and valve back cut to bring the lower lift numbers up, and those 2 things will definitely do just that by a considerable amount.

I will post pics later, maybe tonight, I was eager to see the result and just flowed it 1st.
