it will be a high compression ratio, safe only for low boost, fit a decompression plate or get the pistons skimmed if your cheap or buy proper oversized pistons and get the block bored

Shouldn't skim the 2 litre pistons and decomp plates are at best a bit bodgey. Some people have used Vauxhall C20 LET pistons and had the rod reworked to accept them.
