Thanks rstomhundred for the reply, although celicara45, glenn, confirmed what i need it for. Boosting is not good for titanium valves high heat leads to brittle parts and the auto head has stainless valves. Im going to have cams hardwelded to match the toda 268/264 vvti operable cams. the lift can make serious power up high. Ive seen many mr2 3sgte turn 8500rpm on 268/264 setups with 10.8mm lift. Glenn, do you make anything for the auto head? Id rather support another (the best) beams guru than pay somebody else. Shoot me a pm if you do.
