Recently I had a head swap done on my 1966 Fairlane. I got a mid 1970s large log done up at a local machine shop and had a competent mechanic install it with the original Autolite 1100 using an adaptor plate from Vintage Inlines. The engine runs well and has moderate performance improvements. However, it is pretty hard to get started for the first time each day and any time it sits for over 8 hours, like when I'm at work. It has to crank over quite a lot before firing to life. Before the head swap it started up instantly, every time. Any ideas on what might be the problem? I have a new fuel pump, fuel filter, spark plugs, wires, HEI distributor, all of which were installed before the head swap. I like to change one thing at a time to isolate changes.
Thanks for your input,
