Pistons are SRP's about .020 in the hole. I'd like to be around 10.5 so I can be safe with pump gas but in all honesty am I giving that much up by just putting it together the way it is?



Well your just driving it around..and you don't care about the HP//Yea you can.. Me I have .030 taken off them heads. Are these new heads ..Have you had them checked out ? if they are out of the box new. You need someone to take them apart and check them out.. might as well have them milled then.



This , have the heads cut down to 80cc and have someone go thru them , clean up the valve job, backcut the valves and check the clearance of the guides.

With your pistons ABOUT .020 in the hole you lose the benefit of quench. You could run the steel shim gasket, coat them with permatex copper coat.
