I'm sure someone out there has run into this. I'm going through a pair of 113 heads for my 57 Ford 292 and was wondering. Has anyone replaced the 2 piece valve spring retainers with a 1 piece retainer? Can I use a late 60's 289/302 retainer? They have the same valve stem size and the springs look similar. Not looking to spend a fortune, just wondering if any OEM parts might work. Thanks. Dan
