put a few cossie heads on before, and a shed load of other heads with hydraulic lifters in.......only ever had one or two run lumpy till the lifters pumped up - this common on a cossie when head gets put on with brand new lifters - have to pump up for a bit till they will run properly on all 4?

it runs balanced, it seems to be firing on all 4, but runs dead or flat just like its got fouled up plugs

hoping to get it running again for a while after work tomorrow as its late now

anyone else had the post headwork poor running?
