Potential NF Piston Option??? Engine Experts Help.

[passat TS]

[ Converted text/html to text/plain ]
I want to raise the CR of a NF Engine as much as possible. The target is
11.5:1 but
anything better than the 10:1 I have today will be welcome.

The ideal situation would be custom pistons, but all the places I contacted
want a
minimum of 2 sets ordered.

Here are the options I found so far:

1=2E Find someone interested in split the custom run at around $500 for each
set.
Pistons anyone?

2=2E Stock 7A pistons. They will raise the CR to 11.2:1, but the ones I fou=
nded
are
too expensive. Can anyone find a set for under $600.

3=2E I found at the Wiseco catalog a set for VW 1.8l that has several ideal
measurements. I called them yesterday and the tech person seems to agree th=
at
it
would work. It will raise the CR to 10:8:1. The good thing is that it will
cost under
$400/set, the bad thing is that it has flat top. It has enough material to
machine the
pockets, but that would reduce the compression to 10.3:1. This is the same =
as
deck
the cyl head at $40.
Questions:
   3.1 Can I use flat tops? (valve clearance, combustion problems)
   3.2 Can I use flat tops and deck the cyl head to achieve a higher
compression
without the above problems?

I really appreciate any help, I'm about to finish the head work(last polish=
ing
phase)
and need to make this decision.

Carlos.
