Dart 165cc runner, 1.94 or 2.02 valves?
 

Hello,

After talking to my machinest for many days we are settling on the dart ie ss head, with 67cc Chambers (he will mill then down to 64 to bring compression up. But the small runners should be good for the 1800 stall, 3.55 rear gear and the basically a stock l82.

However my question is this, should we get the version with 1.94/1.5 valves or 2.02/1.6 valves? They are same price so that's not a factor. I plan to change to 1.6 rockers too to help it breath further but I don't want to ruin the bottom torque.

Let me know your thoughts

Get 1.6/2.02 valves. More air is better, they will not affect you bottom end power negatively.
Seeing as how theses are Darts, my experience is that darts run big in their dimensions.
Your 67 cc chambers may be more like 68 to 69 cc's.
Your 165 intake runners may run closer to 170 or a bit more as well.

202's no doubt.

Bigger valve = more power

Buy AFR's and install out of the box - no machining required. And yes, 2.02's like the L-82 has or 2.05's like the AFR's.
