Hmmmm. I can still back out.
I don't ever drive this thing over 4000 rpm (ever) so I don't think it will
affect me there, but I have gone down this road before with the old Elky
engine. I had dished pistons in it, and went to a bigger chambered head and
lost compression. It never ran good again.
I know that the bottom end could go after fixing the top. I have seen it
happen before, but I just don't drive this hard, and I need to stop the
coolant and oil leaking from the head gasket. The valve guides leak in to
the cylinders every time it is shut off too (the biggest problem) and the
plume of smoke at Lions Club, or the grocery store after just 1 to 30
minutes shut down is just embarrassing. Not to mention having to wait for
every cyl to fire properly after the oil burns off. I can't afford to
rebuild the heads that are on it. Plain and simple. I also don't want the
car down for a week or 2 while I am working on it. I just got it back and
the snow is coming.
I am not getting coolant in the cyl or out the tail pipe yet, or in the oil.
Now is the time to change them before that happens. If I wait, .... well I
have been down that road too. I am not interested in driving the Elky in the
snow and salt this year. If I could swap heads in a weekend, that would be
the solution. If these heads won't do it, I have to find some cheap ones
that will. I just don't want the same thing to happen that did with the Elky
and lose compression. It's not worth it to lose flow and mileage though.
More research needed.
