'95 3100 heads on '98 3400...will it work?

[TRayford]

Guy's,
I'm doing an engine for a guy and he needs heads for his '98 3400 Olds Silhoette(forget the spelling!). His heads are cracked and I have a rebuilt set of 3100's off a '95 Corsica. The 3100 heads are reg stamped rockers and his 3400's are rollers. I know I would have to use the guide plates and stamped rockers, but he just wants to get his van running. Will this swap work? Thanks

To get it running yes it will work.

Check the 95 heads because they might have the notches for the roller rockers and you could swap them over. Then, the only thing he'd be loosing would be the larger intake valve, but I doubt it'd even be noticable on a Silhouette.
