Basicaly i can not make my mind up, i have everything bar the pistons for a forged cvh (sold my accrilite ones to go to a lower comp)

but as i was thinking about replacing them, this will be around £500+
i got thinking about doing a st170 zvh and sell my cvh block and rods ect

just looking to hear peoples thoughts on what they would go for as i can see good and bad points on both set ups.

Currently have
OFAM ECU (MS based ecu)
Focus RS Injectors
Big Valve head, ported and polished with matching inlet, 285T2 cam with adjusable pully
stage 3 T3

and a undecided bottomend at the mo, my aim is 300bhp
