Im starting to collect parts to build my engine up over the winter. What i need to know is what cam or cams do i need. Im running BD10s i was told i need to run BD16 or the exhaust side and BD10 on inlet or the other way round i cant remember could someone help me out what 1 or run both BD16. Also the cut outs on the pistons is there a certain size or do you need more info i.e headgasket thickness head measurment etc?

 

Bd10 exsorst is common

 

so all i need to do is get the pistons machined 1 side and buy 8 double springs?

 

Sorry u are asking the wrong person, my spec is standard ex and ab07 in so I can live with out porting pistons

 

Future proof it and do all the valve springs.

Wont you need your head ported to get the most out of those cams? BD16 What horse power are you going for?

Reylands can pocket your pistons.

 

The head has been ported t4 turbo greys already done. Im rebuilding a bottomend and changing cams. Im wanting around 450 460
