My ute has gone and broken another valve spring after only having back on the road from the last valve spring that broke!.The springs that are on the head at the moment are just single springs that have been shimmed up to about 90lb. I'm just wondering what other valve springs other people use in their A series heads as this is the second time its happened so I'm trying to get engine rebuilders to get some decent springs.
Thanks
