I orderd a set of COMP Cams Magnum Rocker Arms that are stud mount and didnt know that my gt40 head were Pedestal mount! Has any one used them with the Crane Cams pedestal to stud mount Conversion Kits with the comp cams magnum rocker arms ?

just send them back and order pedastal mount, using conversion kits are weak as the base still is a 5/16 size diameter

im assuming you got the p heads like me trust me not worth the hassle send them back and get the pedestal mount they arent as strong using the stud mount rockers i did the same thing and ended up buying heads twice lol

Well it may be to late to send them back and they are not p's. The motor is going in my 77 f100 and wont really be pushed all that hard. What brand of Pedestal roller rockers do yall like? They all seem high $$

Minnow, what happen with the conversion kit when you used it?

If you aren't going to push it hard then why bother? I use Ford racing pedestal mount rockers and they work very well.

Lol i broke a stud because they are weak they are small studs although it was my fault because i missed a shift at the track it was my first year of racing

Motorman524 , i would use pedestal mount rockers but i have money tide up in these brand new Magnum Rocker Armsand cant get my money back so i need to use them . minnow81469 . what type of rocker did you use with the kit??

minnow81469

trickflow i mean you can do it why not reuse the stock ones you have anyways the ones off the e7te heads work same 1.6 ratio you dont gain from using the stud mount rockers you gain from the ratio and by the way when u get stud mount rockers you need an intake spacer and the tall valve covers

and you possibly might need new pushrods too
