Toyota's heads flow pretty damned decent as is.

Best I could do on short notice and with windows paint. Hope you get the idea, and don't die of laughter...
Even the G heads are considered a bit primitive these days. The trend is to straighter, smaller ports for higher velocity but still high CFM flow. Narrower valve angle is part of that trend too. Basically during overlap the intake and exhaust valves aren't moving towards each other as aggressively so bigger valves can be used without risking collision.
I think if you look at the LFA's in the cutaway you posted from the magazine a while back, they will look more like the narrow angle high port than the G heads.
