Yup I’d need sleeves which means sleeving and a rebuild. I can’t see spending that money when I can turn the boost down and deal with less power for now. The distortion is causing musical chairs type leakdown as the bores shift against the head gaskets. Every time it was tested, 5-6 times over a couple months, each cylinder could be higher or lower than the last test at the same temperature.
I also want to put upgraded cams and valves in whenever I get sleeved since I can’t do much with the extra boost on stock heads anyways. Essentially it ends up being a $13,000 project and right now my car and all the mods together are just a bit over that so it’s hard to justify when it runs 10’s now LOL.
