Hi all, i've got a couple of questions to ask
i am in the process of changing the head gaskets on my engine, there was more than enough evidence that they were leaking around the water ways i.e getting hot, water loss and a bit of steam from one exhaust.
so off with the heads and sure enough around the rear water way on the nearside head there was signs of leaking (i presume the waterway shouldn't be "sooty" ).
so heads away for skimming (tin off, composite on and enough metal removed to compensate).
two questions, i have read a lot about setting the preload on the followers but i have no shims fitted, do i need them? or do some engines not need them.
the cam i think is a viper hurricane (Andy Pitt might remember), the cam has purple paint on the end of it, can anyone identify the cam by this paint?.
oh i just thought of a third question can anyone recommend suitable ignition timing, standard dizzy with the vacuum blocked off (holley,edelbrock)
