What machine work to get done to the heads?
#11
My machinist did a vacuum test on my heads and the valves sealed so he skipped the 3 angle job, at my request. Runs fine but my vehicle had over 200k on the clock so I anticipated a major engine overhaul within a couple of years anyway. I also did the oil seals myself so I only spent $100 total on head work

I did the port and polish on my heads. The polish is probably only a minor help, but the port job definitely wakes her up. Port match to the gaskets on both the heads and the intake manifold.
You have to remember, these heads were designed for a 3.5L engine and they're on a 4.0 or 4.6L, so they're obviously going to be a little bottle necked.
