360 head trip

I have a set of #974 360 heads with 1.88/1.60 valves in them on a 3 angle low mile valve job and figured I'd do a set by step 'w/before & after testing' sb iron head porting thread.

Here are the as cast INT port numbers for these 974's
.LIFT---CFM
.100.....55
.200.....109
.300.....169
.350.....193
.400.....206
.450.....213
.500.....208
.600.....203-4

I will do just the short turn/bowl then retest, then the guide, the roof and the pinch with a retest after each.
I should have the 1st test today/tonight and see what a lil bowl work does and how long it takes.
Side note: these heads dont have as tall a short turn as the '915 version
Just a couple of pics of what im working with.
