Mopar 400 block 8 sleeves
So steel shim head gasket was a bad idea for this build it seems.
I found clouding in coolant with some oil on the surface. Oil is perfect so high pressure leak I guess.
Car runs really good, oil is perfect, no overheat but it is what it is.
I didnt plug stock oil passages in the block and didnt install the cam bearing rotated to stop oil to heads either. I suspect this is where the oil meets coolant.
I started checking things on warm and cold engine.
Valve lash set at .020" cold is .022" warm for example.
What surprised me the most is head bolts torque specs difference warm vs cold.
When I put it together I torqued the heads to 74 ft lb. Wrench was set to 70 as it should but I verified the specs on it and it turned out to be 74...
To the point. There is big difference warm vs cold so on warm engine its only 62 ft lb. For the 1st time I used Manley head bolts, are they junk or this situation is normal?
I ask about head bolts because I always used ARP and here I got Manleys as a bonus to the heads (they were new). Also I used steel shim gaskets with aluminum heads without any problems till this point. This is 1st time with Indy heads.
I will get thin cometic gasket I guess, but should I get new head bolts also?
Any suggestions? I wan thin gasket to keep the compression at minimum of 11:1.
