I have a guy who has his own machine shop and builds motors, and does stuff for very reasonable. I'm tired of doing the "redneck rebuilds" and motor swaps every 2 months, and decided I'm going to have him do a bunch of much needed motor work. He'll completely go through a pair of later model camel hump heads with accesory holes that I have, with hardened seats, valves, guides and new springs for $230- $150. Compared to other reputable places around here it's cheap. I then started calculating how many different SBC and BBC heads I'd like to have gone through for each of my trucks and realized even with his lower costs (like re-assembling a motor-installing bearings and rings- for $100)... and I'd end up spending like about $2500 in new parts and labor before I would have all my trucks going again. Maybe I'll have to resort back to the 'ole "Buy-a-parts-truck-for-the-motor routine" and maintain my Zero dollar but Lots of Time investment into all my engines. I guess building just one truck does have it's advantages.
