Re: lost valve lift?
has the low lift head deck surface been resurfaced a substantial amount?? try a 3rd head on the block see if maybe you cut that head more than you think you did also try checking all 3 heads on the other bank--- maybe when you decked the block you took off more on one side than the other --- try putting a straightedge on both the head surface and the block deck surface see if for some strange reason they are not flat - do not remember if you said you were checking with a head gasket--- might measure it in several places see if it is the same thickness at several points--look closely see if the rocker arm is hitting the v spring retainer --- I would try one head on both sides of the block see if there is the same variation then swap over 2 lifters then 2 pushrods see what happens---might try measuring EACH cylinder to see if the lift variation is consistent from one cylinder to another
