Ive been told that 1.9 rockers are too big for stock heads.

Ive been told that 1.9 rockers are too big for stock heads.

Anything that provides valve lift of more than .520" or so (I think a little more with the ZZP valve seals) will be too much for the stock head. They don't really flow any better at lifts over .500" anyhow, so if you want anything more, you need some worked heads.

Stock cam or aftermarket?

stock

I think so. That still leaves you just under .500" lift on the stock cam.
From a lift perspective, they should work.

Not to thread steal here but Im gonna be installing UD's AR stage 3 heads and intakes that I got from him and I have th GT1 cam installed now. Im wanting to go with a 1.7 or 1.8 ratio rocker. Would I have to use different pushrods for those?
