now i don't know much about these, hint the questions!

wanting to run 809's so will need a decent bit of gouging in the piston, compression ratio i'd preffer is between 12.0:1 - 13.0:1

so what pistons are avaliable, what is recomended and any scare stories?

muchos gracias ;)

13.0:1 thats seriously high c/r, is there any reason why you would want it that much?

obviuosly you will need solid lifters, stronger valve springs etc otherwise i think you might run into problems.

Accralites are a beautifully made piston, but the available cutout sizes aren't deep enough for 809s. The Omegas would be my choice, available from GMC and/or Longmans.
