Those would be SPFI pistons that have the valve reliefs. These are EA71 Pistons.
I thought about SPFI, but I'm not sure the mapping could keep up with the high compression setup.
And the last thing I want is pinging on the freeway.
.030" off the total intake chamber plus pistons that are a .005"s taller, makes for a fun little geometry project.
Lets just say, if I snugged the head down without the headgasket, there may be piston/head interference.
That pic is a little closer to TDC.
I'll get one either today or tomorrow that's at absolute TDC.
Along with a shot with a straightedge up against it. Just so you guys can see I'm not kidding.
PS: If a crappy little blue wagon kicks your butt getting up to the speed limit, don't say I didn't warn ya
