Diagnose smoke from engine after AFR head swap on TBSS - video!
I am at a loss here. I am not sure if the smoke is billowing out from the back of the valve covers/heads or the intake or whatever.
The heads are AFR 205 CC's I recently purchased from a user here. They have the upgraded dual springs. I have hardened pushrods and a small Speed Inc. camshaft. Everything but the heads, Cometic head gaskets and a new ported intake manifold was already on the truck prior to my head swap and it was working fine. After the new heads and the new ported stock intake - now this.
Ok, I started the camera right when it starts hissing. At first, everything sounds fine, no smoke, no hissing, just good engine noises. Once it starts hissing, the smoke follows shortly after, as you can tell. I am holding the RPMs at 2k during this and you can see the smoke gushing out. I can't determine if its coming out from the rear of the head/s or the intake or whats going on here. I really dont want to pull everything again
Anybody wanna take a stab at what this is?
Thanks in advance.

i hope not. the smoke seems to be coming from the center of the engine. unless both gaskets were leaking, wouldnt you think it was coming from one side or the other. iam stuck. i dont know what the hell to do.

Yup, cross over block offs. Wont do it until it gets warm them its bleeding all of the hot water pressure and going on the exhuast. Pull the intake and put them back on!
