Max Lift with Eddy RPM Heads

[jefflock]

What modifications if any do you have to do to Eddy RPM heads for a .600 lift cam?? 60779 heads

I changed the valve springs..

Yep.^^^^

Little over .700 on my IndyBrocks no mods needed, aside from springs.

I have these Hughes flat tappet cams with eddy heads...

HEV5663AS with 1.6 rockers....gross lift is.626/.642....all I did was install Hughes 1111 valve springs...

HTL6064AS with 1.6 rockers...gross lift is .626/.633 ...all i did was install Hughes 1111 valve springs.

as a note Hughes no longer offers the 1111 spring and has this PAC spring listed...
