unfortunately, i dont have the equivilent test on an SR head, all on the same head/same port, in those small increments like on the 440-1.
but the numbers will still be representative of what you could expect for the various levels of prep.

440-SR head: 4.375 bore, 28" test pressure, radius plate on intake, no flow tube on exhaust.

Intake ports;
A- OOTB std port, zero porting
B- OOTB CNC Maxx port. this is an option from Indy where they CNC the intake opening to MW size, along with doing a CNC bowl blend. no additional porting or valve seat work.
C- this is how i like to prep these heads, so you get the benefit of stepping up from a stock head or RPM type head.
this particular port started out as the CNC Maxx job, then got the chambers ported, my valve job, back cut valves, "bowl ported", guides streamlined, short turns reworked.

lift----A----B----C
.100--70.7/ 71.9/ 74.7
.200-134.2/131.7/147.6
.300-195.2/189.1/212.0
.400-238.2/239.3/265.1
.500-263.6/284.9/305.1
.550-275.6/302.9/319.7
.600-279.3/286.1/329.4
.650-280.3/286.8/336.6
.700-282.3/286.1/343.3

Exhaust ports;

D- OOTB std head, zero porting
E- OOTB Maxx head, CNC bowl blend
F- Maxx head, PRH valve job, back cut, mild full port and polish. this is how i like to do these to match the intake port in column "C".

lift----D----E----F
.100--56.5/ 54.7/ 56.9
.200-104.1/ 95.4/131.4
.300-142.6/131.4/157.2
.400-171.1/159.9/197.1
.500-195.9/182.9/225.9
.550-203.3/192.4/236.2
.600-209.5/200.7/245.3
.650-214.5/205.7/253.3
.700-218.2/210.3/255.6

SR heads ported to the level of "C" and "F" are a good choice for 434-511" motors up to about 750hp. beyond that power level(or bigger displacement), 440-1's should be more cost effective.
