What compression height do you want? And is this a .940" pin or a chevy little end?

im going to check the compression height in the morning.its a .940 pin

If you have a way of measuring your actual block deck height do that. You'll be able to pick any compression height you want as long as you know your stroke and rod length.

I'll be announcing my new ''earlbrown forged pistons'' soon. They might interest you for what you're wanting to build.

i have existing pistons to go of off so i know the comp height. the comp height is 1.225 earl.

Assuming your deck height is standard for a 109, that math puts you about 15 out of the hole. Is that what you want to stick with?

its a 3.8 stage 2 block .it is slightly higher than a 109

Yep, with an untouched 'tall deck' block that math would put you .010" in the hole. Perfect starting point for setting quench using head gasket thickness.
