I am considering to replace the cylinder head for the noted engine. I have 140,000 miles on it . My compression readings taken recently are 131 psi + or - 1 psi between cylinders (which is great. The 2011 Accord shop manual indicates a minimum cylinder head pressure of 132 psi, but does not indicate what the pressure was when new. With a 10.6 compression ration I would expect the cylinder head pressure would at least be in the 170-180 psi range. For the life of me I have searched the internet and cannot find this specification. does anyone know
