I have a 1994 5.7 TBI engine I just pulled from my GMC pickup. It has the 193 heads and I've been told that they are 1.94/1.5 valves. Question is what is the max lift that these heads can tolerate, even if I have to upgrade the valves and springs.
The TBI chambers are like 65.3cc IIRC on 191, 193, and 810 head castings. The HD 810 heads are set up for rotators on both intake and exhaust valves and have larger stem incol exhaust valves. I just put a franken engine in a 1978 Camaro and slapped a marine TBI on top.

Just as stated earlier, you can use a standard intake with the "193" heads.

  • Apr 06, 2018 · These Vortec heads employ a tapered seat like older small-block Chevy iron heads but the reach is longer than the stock 0.460-inch iron small-block.

  • The intake valve seat of the Vortec head has a three-angle grind straight from the factory and the combustion chamber design is a radical departure from former GM heads utilized in the market. The Vortec combustion chamber is a kidney-shaped design that promotes better combustion and will have the spark plug located near the center of the chamber.

If you plan on building anything decent, I wouldn't use the "193" heads. They are a "high swirl" intake runner style of head, designed for good bottom-end torque and fuel economy.
