All the surfaces, cylinders, and the pistons look exceptionally good, and I'm glad to see the cross hatches still in the bores all the way down through the full stroke of the piston.<img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite8" alt=":D" title="Big Grin    :D" loading="lazy" data-shortname=":D" />. The valley of the block had some paint to come off due to where the coolant seeped out of the rubber hose. I took some paint stripper, and grease/wax remover to prep it, then did 2 coats of high heat etching primer. I will do a couple of coats of high heat black paint after the allowed time for primer cure to set up. Isn't she purdy!<img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite11" alt=":rolleyes:" title="Roll Eyes    :rolleyes:" loading="lazy" data-shortname=":rolleyes:" />[ATTACH=full]4609[/ATTACH]  Here you can see the piston at TDC with a .015"-.016" down in bore clearance.   Next time around I want thise puppies about .010" above the deck to get that nice squish everyone wants.<img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite2" alt=";)" title="Wink    ;)" loading="lazy" data-shortname=";)" /> We will have to wait for that on the next build. [ATTACH=full]4610[/ATTACH]   A good shot at the PI's Cumbustion chambers that I done myself with some neat handy work, and not to bad for the first time doing it. The pic really doesn't do it justice of how I made the different transitions between the heart sections of the chamber. I would've loved to have polished them up, but there quite smooth where there at. Each chamber measured at 45cc's, thats 2-3cc's more than stock. The change to a greater CC # is also due to .045" took off from the face of the intake valve margin as you can visable see here.[ATTACH=full]4611[/ATTACH]  It was getting late last night and I had been in the garage all day so it was time to cleanup, and some food time. Before I left I did get the passenger side head tourqued down so I can get some degree measurements and PTVC. Molding clay was applied to the piston for the valve to imprint it, then measurements are taken of the indention with a caliper. The intake valve hits the lower right hand portion of the piston when contact occurs. Always be safe and check if you're advancing the camshafts beyond the recommended centerlines of the camshaft designer. These cams are designed with a 110ICL, I will be advancing them+2* to a 108ICL, and this is to give the engine a little midrange improvement.<img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite2" alt=";)" title="Wink    ;)" loading="lazy" data-shortname=";)" /> I hope everyone is being safe and having a great holiday weekend.[ATTACH=full]4612[/ATTACH]</blockquote>
