It's a pretty big difference. By the time you mill the domes and re-notch, the cost vs. effort would be favored to just getting new pistons.

I have the a460 pistons for my build also, as well as the intake. I had to replace them both, the a460 stuff won't work with my new p51s. I don,t know if they can be cut down or not. Summit sells some Probe pistons pretty reasonable. Mine are dished, 10:1 for a milder build.

You still got the A intake? I'm looking for the newer TFS intake if you wanna get rid of it.

P51pistons

Where the best place to get some pistons for a 521 p51 build. I have probe pistons already. But for the std valve placement. The piston part number I have now is 13599-030
