360 build

Hi guys and girls,Iam new to the site,I have been given a 360 short block its been bored out 030 and o-ringed.The car it came out of ran high 12s on the odd shot of NOS,she also had cast iron heads which are long gone.The oil pan has also been deepened by the looks.The cam and lifters are still in the block also.The pistons are 030 TRW L2405 the only info I can find about them is they are forged low compression for forced induction which it never had or is it going to have.Iam wanting to give her a new lease of life and put it in my A body.Does anyone have any Ideas on these pistons and if Iam wasting my time with these low compression pistons in trying to turn this 360 into a Tyre fryer?
Any opinions or help would be much appreciated.
Thanks
I havent figured out how to post pics yet.
