1.7 rockers
 
Do 1.7 roller rockers need a tune? I am trying to get around 200 rwhp without spending too much money. Trying to save up for a built engine but want some fun along the way.

No they don't require a tune.

I second, no tune required. One of my early mods, and you will note the difference.

are there any that fit under the stock valve covers?

I don't think after market roller rockers will fit. You'll have to research this but I think the stamped 1.7 rockers from a 351 motor will clear. They should be a lot cheaper also.

I originally used Crane Cobra 1.7 roller rockers, and more recently comp ultra gold 1.7 roller rockers, both under the factory valve covers - which I still use. I had to remove the oil baffle to fit the Crane Cobras, and had to grind a little bit to clear the ultra golds, but they fit.

They will give you alittle more lift ! I used the original 93 cobra valve covers with mine. Here's a few pics..

Did removing the oil baffle do anything besides give clearance?

I never had an issue after removing the oil baffle, but I've read other people complaining about it.

So the worse thing that can happen is I need to buy a set of valve covers?

Make sure that you still have some clearance between the valve guide and the retainer.
Also need to check the valve spring for clearance between the coils.
It could get real expensive if this areas aren't checked.......
