Arggh! Headers and too tall head bolts - BBC
Put the motor together and went to test fit the Hooker 2457 headers on the 427 and found the Chevrolet Performance head bolts were too tall and I couldn't get the headers in until I took the bolts out, one by one. The heads on these bolts are too high, I'm surprised because I ordered them from Summit and believed that they were stock replacement, but apparently not. I don't want to spend time grinding off the headers flanges nor the bolts. The bolts have washers which I took off but still a ways to go. So, I'll have to search out used stock head bolts, 4 on each side the lower ones closest to the block. Unless someone has any other ideas?
