bcmohr Posted October 23, 2013 Share Posted October 23, 2013 (edited) Ok, so I have just every part I need to get this project actually running. Special thanks to Wallaby and Vapor Trail for the engine parts. The heads arrived on Tuesday looking like this Edited October 23, 2013 by bcmohr Link to comment Share on other sites More sharing options...
bcmohr Posted October 23, 2013 Author Share Posted October 23, 2013 I got the heads into the shop today and tore them down. They were in pretty good shape, one cylinder looks like it might have been running lean. The springs are dual springs and in great shape. Link to comment Share on other sites More sharing options...
bcmohr Posted October 23, 2013 Author Share Posted October 23, 2013 Next came some pretty work. I figured there would be all sorts of casting under these valves to hog out and blend in. I was wrong. Being that this is my first EA81 build, had to learn a little as I went. I sure wish that the intake runners were siamesed together instead of the exhaust Theres no good way to get flow through these heads and not much material to change the flow characteristics. Theres a tiny pile of shavings from doing one head, thats probably 90% of the material that I took out. Then it was time to cut the valves and smooth out the combustion chambers so when I add the turbo, there are no hot spots. Link to comment Share on other sites More sharing options...
bcmohr Posted October 23, 2013 Author Share Posted October 23, 2013 Heres how the valves came out. The valves are 1.65 IN and 1.375 EX, larger than I thought they'd be which is good, something needs to flow in the little motor. I turned the intakes valves at 45 and 20 degrees The exhaust valves are 45 and 30 degrees All but one valve was in great shape, just a little bit of hammering on an intake valve that cleaned out quick.

bcmohr Posted October 23, 2013 Author Share Posted October 23, 2013 I have some more work to do yet, have to get the heads planed, turn the seats, blast off all of the gunk and then they'll be ready to bolt onto the NOS 1.8 block. Looking good so far. These build so much faster than the V8 fords, chevys and olds motors Im used to. Link to comment Share on other sites More sharing options...
