Stock bottom end.

B-303 with 1.7's. heads have 2.02 intakes.

if you have run this combo please let me know if they hit or not.

 

were those with 2.02 valves?

 

2.02 should most likely fit. the total lift and duration of a B cam+ 1.72's shouldnt be much more then the F cam on 1.6s

 

We are running a F-303 Cam with 1.6 roller rockers. And we dont have any clearnance problems. We spoke with Ford Motorsport last year and they said that we can run the 1.7 rockers without a clearance problem. If you step up to the X-303 Cam then you will definetely have to be careful and check your clearances

 

Always use the putty test. Especially when in doubt.

 

+1 on play dough.... Is it stock block, stock heads? Or have they been mahcined? You shouldnt have any problems, but its always better to check...

 

don't think it's a cam and rocker issue, It's the 2.02 valve.
Steve I don't *think the 2.02 will clear it.

 

trickflow wedge heads have 2.02 valves dont they? they bolt right on to a stock shortblock with a .499/.512 224 duration cam, as a package... i think the 2.02s will work out, just playdo it
