I am not an engine builder - more of a part & gasket changer guy - but fitting the intake to avoid gasket leaks and center it so the distributor seats properly seems to raise a lot of issues. Fitting and sealing up the rear main seal seems to be challenging. A machine shop that knows FE machining to get the block, heads and intake to all fit properly is a must. And not the least, understanding all the center oiler, sideoiler, low rise, med rise, high rise, tunnel port, terminology and interchange potential is a learning curve. I would venture that if you have built a number of other engines you will be able to manage it. But an FE appears to be a poor choice for a novice engine builder. The expert/professional FE builders are very appreciated for their knowledge.
