There seems to be a price war in my area on Edelbrock alum heads. I can buy Victor Jr 23degree cheaper than Performer RPM and just wondering if the Jr's would be ok for a primarily street 350 9 1/2 to 1 comp. 224/[email protected] Summit cam Weiand Stealth mani & 600 cfm Holley Petronic ignition, balanced etc. with 2500 stall converter. Also what does the 23 degree refer to? Valve angle? Plug angle?
