4AG head flow values
Hi,
I found http://www.kelford.co.nz/cylinderheads.html it has flow figures for a 'rally' small port 16V head. Has anyone out there got any more links / flow data for the differerent 4AGE heads.
Cheers, Nick

Interesting - it looks like the most "efficient" exhaust lift was .25"(6.35mm)
Strange that that's not factory - they could gain a small % more efficiency if they bothered to use softer springs.
