VVT should not cause any issues. Also, the 20V head does not use TVIS butterflies, only the earlier model "bigport" 4AGEs did. For a forced induction set-up... the butterfly system is rendered almost pointless, so removing them can help flow, but the bigport intake ports are a little bit too big so low-end suffers slightly. As for the issue of ITBs, so long as you use the stock box that covers the ITBs, with or without the stacks, you should be fine.

was the gze head direct bolt on? And i'm not going to get into a supercahrger Vs turbo talk i like turbo and just want to stay turbo the i really would like to do what Ray Hall did 20v 7agte around 250-300 whp

The gze head is essentially the same as the regular 4AGE heads. The earlier MR2 4AGZE used bigport heads, and the AE92/AE101 used smallport heads. I believe the early AE92 models may have also used bigport heads. These are typically the AFM 4AGZE. As for your question, the head essentially bolts on the 7A block. The only concern is using the correct headgasket (4AGE/GZE/20V headgasket matching the head). The headgaskets correspond to the layout and waterlines also...
