Hi, i am thinking of getting roller rocker arms on my 94 gt and i was wondering if it requires new valve coverms and many fold spacer and causes hood problems like on 89. Thanks you.
When I went to 1.7 roller rockers on my 94 I had to get taller valve covers, this bought about the need for 3/8 spacer kit for the upper intake. It would also be a good idea to get some sort of after market hood. It will fit under the stock one but its gonna rub.
There is no need for a new hood. Buy a set of Fox body valve covers and grind some of the supports out of them. They, albeit barely, cleared my Exploder manifold with no modifications or spacer gaskets. These Fox covers will clear any rocker arm style available.
