I recently purchased a 74 914 with what I thought was a 1.8l engine with low compression on all 4 cylinders. My plan was to get the heads cleaned up and have new valves and guides installed and replace the pistons and cylinders with a 94mm set. After removing the engine, I found that the block does not have ID numbers in either location, the heads are 2.0l bus heads 022 101 372G and the pistons and cylinders are 94mm. If it is a bus block, the dipstick has been relocated. I also have a 1.7l long block W0093163 with 022 101 372 heads that is also in need of refreshing. So, should I have larger valves (42mm/37.7mm) installed in the unidentified (possibly bus) block and go with 96mm P&C's or go with the 914 1.7l block and have the heads opened up to accept 96mm P&C's and maybe have larger valves installed as well? Either setup will be fed by Weber 40 IDF carbs. Thanks in advance for the advice.

Thanks LarryM and JCD914. My 2.0l bus heads have oval ports.
