and what about the 7105139 ?

they are intake 275° exhaust 267°
intake lift 10mm exhaust lift 9.50

actually i was thinking around 170 whp?

there's the trouble I personaly wouldn't risk running 170whp on stock internals certainly not on the early bigport ones without at least treating them... using internals that have done a 100k miles already and then squeezing out an additional 80% power is pushing it...

and as mentioned befor catcams are quite steep... HKS 272 cams have 'only' 234° @1mm lift whereas this would equal about 264 duration for Catcams - so it's realy up to you just remember the longer the duration te later it'll produce any useable power in the revrange... as a guess I'd say peakpower (depends on a lot of other factors aswell) with the 139s would be around 8500 or even later... usualy you'd want to have peak power at Xrpm and redline at X+10%ofX
