Notch the bottom for the oil squirter.
I made a reliable 450 whp on a 60-1 log manifold .det pistons at 21'psi

why would you get rid of a ve head(best option) for a de head to lower the compression when you can change pistons...

with an almost identical setup i made 380whp at 12psi...with the 8.5:1 pistons, and a VE head the compression ratio will actually be 9.3:1(the head will raise it .8)
if you want specifiics on my old set up pm me...ill be more than happy to share

Not trying to thread jack, But I'm curious about something. So saying that u have a DE block and use Fgorged pistons with a 9:1 compression ratio and a SR20VE head, then the compression ratio should be 9.8:1. So best bet is using 8.5:1 pistons and a VE head to get 9.3:1 ? Am I right in thinking this or am I missing something somewhere ?
