Rocker arm Question

[cheese_05_70]

I was brain storming and I thought about how most cams have a split intake and exhaust lift value.

So is it ok to put 1.6 rockers on the inake and 1.7 on the exhaust?

If this is a stupid idea please let me know.

I have a:
306 motor
vic sr. heads 2.02/1.60
1.6 rockers
E-303 cam
Typhoon intake

Anybody?

or would it just be better to use all 1.7 or 1.6 rockers?

That's an old school tinkering practice to increase the performance in a setup where a single pattern cam is used. In terms of what would be better for your setup, only testing will provide you with the data... some work better with 1.6/1.7 others with a 1.7/1.6 split setup. Is it better and more cost effective to go with the correct camshaft events nowadays?.... obviously.

Thanks for the reply.

Well I have seen flow numbers on heads similar and it seems like they are weak on the exhaust side. They are already port and polished and I got it tuned and my numbers were low I thought. 256hp and 285tq but I also need a catback exhaust.

Anybody have any other thoughts on this?
