Re: 441 heads
I got a little flow data for those stock heads,, at .400 lift they flow 194 & 127 cfm intake/ exhaust @ 28" water. At .500 lift they flow 201/146 respectively. Thats not too bad,, with in 72% of each other.
The 461 head flowed better and ported even better and thats with 2.02 / 1.60 valves. Just thought I would throw that in .
