NOS Edelbrock 6089 heads, flow data?
Hi all, first post.
I know these heads are old but I'm trying to find the flow numbers for them. I think they are the 170cc intake runner with a 64cc combustion chamber, 2.02/1.60 valves.
They are the built RPM Performer heads and are not the current 60899's.
Any one have a definitive answer for me?
So far I have found the following sets of numbers but I know the first set is for the new heads but am unsure about the 2 other sets of numbers.
Lift Int Exh
0.1 67 58
0.2 130 108
0.3 183 144
0.4 226 169
0.5 229 175
0.6 232 182
.050 31 23
.100 64 51
.200 129 104
.300 181 132
.400 218 157
.500 237 173
and finally,
0.1 65 54
0.2 127 105
0.3 180 137
0.4 219 155
0.5 240 163
0.6 236 167
So, any ideas?

I bought a set of these in the late 90's. I flowed them locally & I believe they were close to your 2nd list. The intake port tract measured 185cc OTB. On my 385 they were done by 5600 rpm. Mild porting raised them to 6200 more porting let them turn 7000 rpm easily.
