would be the same cam the beehives are being lifted by now. .512 on ex and in. All I wanna swap are heads and was wondering if the old springs would physically fit n workDepends on, the cam you are running and how much lift the springs are rated for.
I dont think y'all are getting it... The cam I'm using now will be the cam I'd use w new heads. The springs I'm using now would/will be the springs I'd use on new heads IF THEY WILL "Bolt down" TO NEW HEADS. I know the cam lift 512 on in and on ex .. All I want to do is reuse those springs on a different set if heads. The cam will not change. All I'm wanting and needing to know is can springs used on e7 work on other heads. I'm wanting to take the springs from the e7s (that work w the cam) and maybe put them on a set of eddy e streets. Now my question is are springs inner changeable from head to head or is there say an e7 spring, a tfs type spring, eddlebrock, etc etc?? If I'm thinking correctly the only reason the e streets can't be used or not recommended to be used w roller cams is due to crappy springs.Even if they physically fit, may work for a granny shiftin' mofo but one good romp on it could throw it out out. You need to know the cam lift and if the spring can actually handle handle it.
That's a bad area to take a chance IMO.
Should be fine if they have that low of mileage. Have them checked to make sure. Dropping a valve = exploded piston. Ask me how I knowWould be kinda cool if they would work. They're pretty good and I bet they don't have 5k mi on em
Will do, I'm using a comp cam myself.Check out Crane's website, or Comp Cams. There are a lot of little things to think about with springs (I have been researching for my RHS heads and new cam). The spring has to fit securely in the valve spring pocket. There are acceptable clearances here. The springs have to be installed at a certain height to maintain correct spring pressures. This can mean using shims and a specific retainer. The retainers also have clearances regarding how their bottom sides fit into the springs. Retainers for the E7 heads will most likely not fit the Eddy's because of valve size (ex: 11/32 valves vs. 8mm valves/example only).
Now, I am still figuring this stuff out myself, so I can't give you all the definite answers. But there is more to it then swapping them over. Do some research and checkout some of the tutorials on the websites above. You will probably be able to figure out what you need.
Good luck with it.

the tech guy from eddlelbrock said no roller came w e street. I think originally they were marketed for "modern" budget minded mustang drivers but I believe they were getting complaints bout valvetrain. So I guess the savings came from crap springs. So anywho now they say they are for flat tappet cams only. More than likely if I get heads I'll prob go another route vs swapping over my e7 beehives. But we shall seeAlso don't skimp on valvetrain. Cheap insurance,high end stability,more power. You can run the e streets factory springs with that cam btw. They are good to somewhere around .540 lift if I remember right

Well learned something new.Will do, I'm using a comp cam myself.

yeah upon futher research those heads def not they way to go. By the time you got the valvetrain decent you could've got a better headWell learned something new.If I were you I'd just spend a little more and buy better heads then. Lol. Or go the gt40 route
