Somedays if it weren't for mistakes I wouldn't make anything at all. It was slow and painful tonight but head 1 intake springs are setup and I'm pretty confident they are setup right.....and equally confident that last build they were not....but that's in the past, the new me triple checks and sets everything up right

Outstanding. Now I need to get on some porting and spring set up as well. |

I'm so glad I'm not paying by the hour! Just stupid liitle stuff...a bur here, the retain sits a little height after the spring is shimmed so it need a taller shim, when I replaced a bunch of valves why back it looks like the endmill I cut them with was dull and I didn't clean it up properly, finding a bunch of those Attachment: Attachment: But head 1 is ready to have the shims set I think...yay Attachment:

For comparison, here's what the stems I lapped right the first time look like...no bright shinny spot just a little matte finish across most of the stem face as they should be.

It thought I'd be posting a pic of 2 finished heads.....but on the very last valve I realized then remembered when I opened the spring kits there were 2 kits with 1 retainer design and 1 kit of another....they shortened it about 0.5mm and I measured the shorter one for my setup math. So I now have 16 springs set correctly and 31 set .05mm loose.....time to start over Most are on the tight side so I should be able to drop in an .015 shim and be good SHOULD Attachment: ..... and the kids noticed a long dead mouse under the pedals......

I needed a better welding mask than the Harbor Frieght ones. I was going to buy myself a nice Lincoln but started looking at reviews and came across a bunch rating the Yeswelder LYG-800HP as having great features and optics. It is one of the cheapest masks at $59 to offer True Color and a large viewing area. It has replaceable batteries which I really like and it comes with a spare battery and a couple spare inside and outside lenses and a nice helmet bag to store it in. It has a 3 position switch for grinding, cutting, and weld. I used it yesterday in the cutting mode for gas brazing some cast iron and today for doing some TIG work on mild steel and I was able to see everything much clearer. Mark, if you are down this way anytime stop by and give it a try. Hopefully I'll get to try it out on some aluminum soon. Best mask I've used. Extremely comfortable as well. Give one a try. |

Did the math backwards in my head....it was pull it apart and cut .020" off the bucket, remeasure, reassemble and 3 hours later....finished heads.

Does that mean that they're shinier now than they were? |
