Hey guys and gals,
I recently put a new head (pro-topline) and headgasket on my 1990 Isuzu trooper. After assembely it dosen't hold an idle and will stall unless above 1500-2000. It also smokes like crazy and I believe this to be the system to the right top of the engine with the tubes that go to the exhaust ports on the head. Any ideas, ways to troubleshoot or any advice would be appreciated.

Thanks in advance,
