it wasn't my head it was my fuel pump, my head is wildly ported, i do not genuinly believe a t34 is capable of making over 400bhp for very long! and they definatly will not make it with a -31 actuator.........

spec
is l+b bottom end
7.2-1 pistons with valve pockets
bd14 +bd10
isky springs
big port head by karl norris
polished and peened rods
arp everything
back pressure boost control

my engine is 400specced but i wouldn't sell it for £5k..........too much love's/money's gone into it
