Notching Pistons
#11
So are you saying to avoid high lift i am using boost. I do have a procharger and am looking to find out if its better if i use high lift option and notch the pistons. I have not rebuilt the engine yet and am trying to determine if i should wait or get the heads now. If i notch the pistons i have to wait. Is high lift that much better?

+1...i'm not sure he's getting this either lol.
OP, you really need to clearly define what it is that you want to do here. Do you definantly want to do heads? If so what type, or just a p&p. Do want to replace the intake as well, since you'll now have different heads and cams?
All these possible scenarios will determine what lift, duration, and lsa would be optimal. Cleary you should run blower cams (and better valve springs since you're boosted) but what exact specs will be determined by the rest of you're setup.

You can notch your pistons while they are still in the block, there is even a tool you can buy to do it. It is very time consuming and you have to be very careful while doing it. Can it throw off you rotating assemblies balance? It may.
