report on the cc
they are a going to be larger stock
also put on a block and scribe around the bores if you plan on unshrouding the valves
Report on the CC! Yes sir, got right on that. Here ya go:
"they are a going to be larger stock": Not sure if this is a statement or a question that the chambers would be on the high side at 64-65cc. What did you mean?
Now keep in mind I am 70 years old and my eyes are not what they used to be and the markings on my burret are a bit hard to read. I only measured one head so far and they measure 62, 62.8, 62, 62cc. The 62.8 chamber I am positive is a measuring and operator error. The valves appear to have been done sometime not too long ago so at least a surfacing on the head face was likely done. I have no way to determine if the head was milled. I removed one exhaust valve for inspection. Cannot remove any more cause my ancient valve spring compressor finally gave up and died. It was my grandfather's. I'll give it a suitable "burial" by hanging it on the wall in a place of honor. Motor appears to have run very rich or maybe using some oil based on the amount of carbon buildup on the valve stems on the chamber side. Did the finger suction test and valve stem wiggle test for valve guide clearance and that specific guide seems just fine. Valve stem seals are umbrella style and not brittle, but maybe not sealing as well as they should. Makes no difference, I am doing a valve job anyway so at least I will know where I started.
I have a set of KB167 +0.030 pistons on the way. That will put compression about 9.5 or so, which is where I wanted to be.
I have no plans to enshroud the valves. For my use, the heads will be just fine as they are.
