Hello, I recently discovered what brand heads were put on my C5 when I was doing some work. I saw the mark LPE and then LS644 and LS645 on the other head, then what looks like a serial number. Do you have any info about these you could give me. They are 2001 heads, I would just like to know if they were the GMPP heads I have heard about or in house LPE done and if you had records if they were installed by LPE or sold as parts OTC. I got Mallett reciepts with the car for other drivetrain work, but I did not know if they used your heads or not back in 02-03 when the car was done. Any help you can privide would be great. THANKS!
