Contacted Rocker arm specialties and spoke with Randy. Great guy and very knowledgable. He is going to try to fit the 1.75's off the Buick I8 and get them closer to 1.6 as Charlie from Camcraft suggested. Will let you know how they come out. We have a customer in now who had 1.8's made for his Olds Rockett 88 324. They look OEM until you set them side by side and mic them..... fabulous job!
