I'm not using these heads, but i have a ZC Fairlane with a 347. I've got Pro Topline 180cc heads and a Comp Cams 31-335-4. I'm currently running 12.8 at the track with a busted auto. Plan on getting into the high 11's by the end of the year. If you want any info i'm glad to share it.
well thats the excat cam as well!! how about that!
I was looking at the pro topline head but were told buy the shop thats building my motor (john white racing) that the casting and port work wasnt to flash and that the world heads 180 were better I thought the 200 would be better for my aplication. Or maybe even the edelbrock performer rpm heads? How much extra port work did you do to achive what you got? And what price did you pick them up for?
Sorry guys Picked up my Edelbrock heads And I would like to know if any one else has noticed the shoddy oil return hole drilled into the heads?? they have burrs and metal shaveings around these holes!!! anybody else got or noticed this? I will try to post pics latter.
