if you have a 100cc you can use a flat top piston .if you have a dish that should jump it up or a close chamber pistons you may have to trim the chamber out a very small amount to clear how much CR do you want??? at o deck with a flat top you should be at 9.3 . with a close chamber dome piston base off 101cc head you will be at 13.5

Not sure exactly where I am wanting to be on compression. Just wanting to put together a decent motor that will Push a 84 Monte down a 1/8 mile track. I had a 11 to 1 360 Chevy with double humps and was wanting to try a Big Block.
