Can beehive valve springs be ran on 452 heads with out modifications?

RacerHog

Chevys Yes...... Mopars No....
I would advise you always check spring when swapping.....
Are you having Valve Retainer and Rocker Arm Clearance issues your trying to get around?

mizzou580

No I don't want to have to machine the heads if I don't have to. I know I will if I use the dual springs.

I was told I might have to because of the spring seat OD.

RacerHog

That would be a 10-4...

You might look into PSI Performance Valve Springs... Or Look into K-Motions
For what you need....

They're out there, Comp Cams makes them for Chrysler B/RB.

So many out there if you look through a few catalogs with your measurements you'll find some at the right weight. I found some for a smallblock with retainers cheap, from some GM engine.

It's not that expensive to have the valve spring seat pockets cut, at least around my neck of the woods. But if the motor is together and you dont want to pull the heads to have them done.. You might try a see if a set of Mopar performance springs might fit????
Just food for thought.

So true Bob. I have a cutter from Comp and hand held cordless drill worked good.

I'm looking at the beehives to get under my aluminum rockers rather than notch the rocker. This is the only reason I'm looking at them.

I know there run on some of the Edelbrock heads. But when it come to the Mopar Iron head. Most I have seen have had to be mod. But you know how the industry changes.... You never can tell whats coming out next week....lol

FYI.. Mizz.... If you do have to have the heads reworked for the spring seats.. Have the Valve Seat Pockets back cut 30*.... That will give you some free H.P.

Just food for thought....
