Thank you for the picture of your SD-455 pan. The pan on my engine looks exactly the same with the exception of the 5 tab lip for the later seal. PO said that was the PMD replacement pan in the late 70's when he bought it. So they had already purged the 3 tab pans from the parts inventory I guess. Steve25: When I take the heads apart, we can talk some more and I will take pics and get measurements you are interested in. My plan is to just clean them and put them back together and check the springs. The original invoice from A-Hines says guide liners were installed. No other real details. Very hard to read. Hand written and 40 years of faded ink. Heads are assembled and bagged. Probably be a month to 6 weeks before I can get to them. I want to get the short block back together first.
