New Block # 25524140

[Franks86gn]

I just recently picked up a 20 bolt pan N/A engine # 25524140. After some research I discovered the deck height is different than the 109 block.

I'm rebuilding this to use as an 86/87 application.

Pistons: Can I use TRW 2481F pistons ?
Head Gaskets: What head gaskets can I run to acheive stock Compression Ratio?

Any other info on this block or rebuild tips?

Thanks,

RJC makes a steel shim gasket that would work fine for this.
