Im hurtin for cash, and i want to get more ponies, i was thinkin about heads but dont have the cash right now. So i have some questions.
1. i have stock heads, will i gain much hp if i go to different rockers

2. if i can what ratio can i go to? i have a E 303 cam, will 1.7s make my valves tag the piston?

3. what brand makes a good roller rocker set?

4. also on my setup would it be safe for me to go with a 125 shot of nitrous ----- i have stock lower end and edelbrock intake, holley 600 carb, E 303 cam, and hopefully rockers

i apprieate any info anyone could give me.

Get yourself some ported E7TE heads, check for piston to valve clearance. Your pistons don't have valve reliefs and I don't know if the E cam will have PV clearance issues with the E7 heads.

Do not add 1.7:1 roller rockers. Your heads are not going to flow enough for them. They actually don't flow enough for the E cam. 1.7's will put you at .530lift.
