this is nuts. i have 80rwkw at 6900.
4age 20v bottom, bigport head. 40 Webbers.
standard everything except .8mm TRD gasket

i think you needed to dial them in just a tad!

on a personal note: anyone happened to check valve/piston clearance with 20v pistons and bigport head? (hahaha)

I think im just gonna buy some 264/270 8.1's and see what happens...
