Hey guys.. I got like 6 or 7 months before I plan to do my tear-down and mild-rebuild and restore to my cars engine bay and motor. Its currently ford blue and although its fine and functional its not my style.. im going black and ceramic/silver with nitrous lines as accent lol... (Anyways sorry off topic..)

I'm going with the GT40p heads and some sort of upper and lower.

How do I convert or install these rockers?

Will they be safe? I know there ebay but they guarantee them and I won't be pushing 450whp. Probably close to 400 on rebuild with nitrous.

I mainly like the fact that they're billet blue. I can get the crane 1.7's for like an extra $40 and I know they're reliable but can these ones be used?

Also whats the stock ratio? Says these are 1.6 and the crane ones I saw were 1.7's. How do you convert/install roller rockers? Do you need to do anything besides install them? Do you have to disassemble the head to install them or just remove the old rockers and screw these down?

Thanks for the input. Coupe you seem to be really intelligent and help and I appreciate it.

Also.. I was thinking of switching to carb from EFI. What am I looking at paying for a used intake (Would you suggest like a used edelbrock or is a stock one sufficient at all?) and a used 650CFM carb? I'm not nec. asking what will it cost but whats fair pricing if I go around looking to buy them used?

Thanks guys!!
