you have very basic problems here.
wasted time and effort
get two identical heads that are equal on the dyno.
carve one with grooves, measure the vol removed.
remove equal volume from other chamber so test means something.
repeat dyno results.
If this is too much money or effort, don't proceed.
or carve one head up with a control groove:
overall, remember that a half assed bad test is just a waste of time

no, it isn'tI have realised that my engine is the perfect testbed for a specific engine modification that the TB community has been arguing about for the past decade and a half.
Will you be milling the head to compensate for the volume the grooves take up? Easy to improve detonation resistance if you're dropping compression.
So, you are unwilling to actually do the test that is needed.1. Milling the head would require first CC'ing the current head and then shaving appropriately. I lack the funds and/or means to do so, as die-grinding the head to a certain cc would be significantly more expensive than shaving a specific height from the head. If I can receive support in this venture however, this would be a great addition.
