Best Years for the 318 LA?

I had my head guy install 360 valves with hardened seats in my 920's and port them...

They will flow just as good as a stock 340/360 head and have the smaller combustion chambers for the compression increase...

Yes. In fact, you can take any 318 head from '67 to '91 and add larger valves, and good port work and really increase flow. If you have to pay for it all, it's $$$ though. Especially today.
