Here’s a good one. What about the guys who have previously built their bottom ends with 9:1 DET pistons and want to ditch the DET head to utilize the P11 head? Also using a 1.1 HG. Will we have any valve/piston interference issues with stock p11 cams? Or must it be 8.5 or VE pistons at 9:1 with valve reliefs?
What does that do for final compression ratio if using DET 9:1 pistons with a VE head?
