Maybe not 10 compression

Any Low pressure turbo head with VVT should work-This means XCs, GLTs and LPT C70s. Use the VIN code to help: characters 7 and 8 should be 56 ex: YV1NC56xxxxxx where YV1=Volvo, NC =C70conv. 56 = LPT motor. after that come emissions and serial numbers. I expect 1999-2000 perhaps newer as well. From what I've heard, the head is the same for the N/A cars as well, the compression difference is in the bottom end. If so, any non HPT, single-VVT head should work. edit: basic heads are the same, differences turbo heads use sodium filled exhaust valves. cams are different between variants. If you just need the core head, it looks like your choices open up to any single VVT head.

Non turbo heads have no VVT in 99 and have VVT on intake (not exhaust) in 2000 and above so beware.

Which engines are compatible for replacement for the 2.4 lpt vin code 56? it is a 2001 model in a c70 conv.
