I've got a set of '93 Cobra heads that I'm really itching to slap on my '95 vert but I have some decisions to make. The heads need rockers so should I get 1.7s, 1.6s, or 1.72s and stick with the stock cam or should I get a cam and just transfer the stock rockers from my E7s over to the GT40s? I guess as a final option, I could do cam and rockers but that's all the work of doing the cam swap plus double the expense of just rockers with stock cam. I'm on a budget build so what do you all think is the best bang for my buck? In the end, I think I will end up with shorties, catted x-pipe and either Flowmaster, Borla, or Mac cat-back. Intake will be Explorer GT40 style and someday maybe a Kenne Bell. I'll also be doing a gear swap to 3.73s soon.

With any cam, there is a recommended rocker size to go along with it. there is no reason why you should stay with the stock rockers after a cam swap. Since you already have the cobra heads i would put those on to start off. I its a budget build and wont be buying a cam for a while, then put the heads on and get used to your car with only those.
I have come up with some more specific questions that might be easier to answer and will still give me good info to help me make my decision.
1. With GT40 heads and Explorer intake, what kind of HP gain would I see from 1.7 rockers alone with the stock cam?
2. With GT40 heads and Explorer intake, what kind of HP gain would I see from 1.72 rockers alone with the stock cam?
3. With GT40 heads and Explorer intake, what kind of HP gain would I see from 1.7 rockers in combination with a TFS1 cam?
4. With GT40 heads and Explorer intake, what kind of HP gain would I see from 1.72 rockers in combination with a TFS1 cam?
5. With GT40 heads and Explorer intake, what kind of HP gain would I see from stock rockers in combination with a TFS1 cam?
