Well here are what the codes are.'
P1641 Fan Control (FC) relay 1 control circuit
P1642 Fan Control (FC) relay 2 and 3 control circuit
Wild guess but maybe your fans aren't kicking on and the engine getting real hot which would hurt the engines performance. Did you use the proper pushrods with the heads like they recommend? There is a bit of a length difference.
Sorry I can't offer more help.
