Thanks for all the replies hut I think it got a bit off topic with the VE heads.
I've ended up getting my current SR20 built by Donny who many of you would know and I thought it wouod be the best option now after considering your replies.
The main reason was that its a street registered cwr and I don't want it to get engineered as that would blow the budget. Secondly I know that this Sr20 is fresh and forged and will be able to handle track days with that power and should 'hopefully' be fine for a couple of years.
Donny recommended this for the power im after:
Acl race bearings
Cometic head gasket
Nissan oil pump
Nissan water pump
Nissan gasket kit
BC valve springs
BC cam gear and cams being dialed in.
Block and head machined, tested, valve stem seals etc.
Any input for the brand choice of pistons,rods and head gasket?
