Custom VALVE work!?

ok, I've been thinking about having my head ported, and putting in the catcams cams, and have recently found out that I can only use Intake cam due to the VVTI on my GT. I was thinking abouty it getting custom valves made to get some better airflow through my 1zz. I was thinking about going 2.02" on the Intake valves, and 1.65" on the exhaust, but I'm not sure there is enough room. What do you guys think? ANyone with any info or opinions is more than welcome to post

no one really knows, 2.02 is huge and i can tell you that wont fit, your talking about 2 inches in diameter.

the shop that you take your head to for work should know how far they can enlarge the valves safely and what kinda port work they can do to increase its flow.

gt head suffers the most from poor flow characteristics, and would benefit the most from a correctly done p&p.
