There are allot of places to get pistons, allot of brands too
If your going for a flat-top piston with valve reliefs,
to keep it around 10:1 -10.5:1 so you can easily run pump gas, no worries,
I'd suggest to try to get a piston with as close to a zero deck
{flush with the top of the block} as you can,
it will aid in quench area/flame travel somewhat & to stay at about 0.040"
with a 0.040" thick {appr. 4.340" bore} in the compressed & torqued head-gasket,
it does depend on your current deck height,
whether the block has been squared &/or deck ever before,
most of the off the shelf replacement pistons are like 0.020" to 0.040" down in the cylinder,
8.8:1 or less compression with a 88cc chamber & 0.040" head gasket
you could have the heads & intake, shaved/machined &/or the block decked/machined
to compensate for too much down in the hole...
A "dome" style piston, much more important to have a specific shape dome/piston,
that needs to be specific for the combustion chamber style, size & shape, of the Eddy 88cc RPM heads
even with the larger intake & exhaust valves, specific valve reliefs, will generally need to be recut...
contact
Mancini Racing they can help you,
here's an example
http://chucker54.stores.yahoo.net/manciniracing6.html
they have a few different to choose from for a 383 with a std. 3.375" stroke
they have a few
Diamond Racing forged pistons
ranging from 9.8:1 with stock length rod & 72cc combustion chambers
{with an
88cc chamber with the same pistons, it would be far less static compression, like 8.8:1}
up-to to like 11.1:1, depending on rod length, pin size, ring thickness & or bore size etc.
common sizes in like 4.280" {0.030" over} to 4.310" bores {0.060" over} 4.25" is std bore
Diamond, KB, ICON, Mahle, Wiesco, Venolia, Sealed Power, Speed Pro, Manley, JE, Probe, Ross etc. more too
lots to choose from,
almost any custom pin size, dome or deck heights are more money thou too,
depending on which rod length {stock 383 rod 6.358"(or 6.36") or 440/Hemi length 6.768"}
you ultimately end up choosing also,

look under pistons
I guess it depends on your "actual" budget & how much your willing to pay for getting the right
type/style shape & size of piston & compression ratio combos...
quality properly fitted pistons aren't cheap !!
generally a compression distance/pin height
from IIRC like 1.868" service pistons {low comp.} to 1.908" to 1.920"
depending on company, material/style & whether it's with a std rod length etc.,
allot of variables here...
good luck, happy Moparing
