Petter Exhaust Manifold Flange 1" BSP Petter P/N 250438

The manual was delivered promptly, excellent customer service. The manual is clear and helpful but not overly detailed and there are some basic diagrams but not over-many....the manual assumes that the user has some pre-existing moderate basic mechanical abilities and a good range of tools......there are instructions and measurements given for various settings and troubleshooting, but when i went to find the torque setting for the cylinder headbolts i did not find it....torque settings seem mostly absent...there are very scant references to things like gasket sealants and anti-seize applications/coatings...no particular mention is made to coolants except that water is used, i did not see things like references to corrosion inhibitors or other things like lubricity enhancers...the other thing i noticed is that there is some correlation with aftermarket 'listeroid' engines but not a close correlation since there are several variations.
