14102193 this is the casting number for these heads? are they 350?

 

so i see that it says 1.94/1.5 valves and its for 305-350. but is it the same as one a regular 350? found some heads for cheap, just want to make sure that they're worth the time and effort over my stock 305 heads.

 

They are primarily 350 TBI heads. Stock for stock you probably aren't gaining that much other than a slight drop in compression.

 

gracias.

 

As Stekman said, they are basically the same head as you currently have on your car now (187's) but they have larger valves (1.94/1.5 x 1.84/1.5 and chamber size (64cc vs 58). There is no need to swap to them. They were used on a multitude of LO5 (350 TBI) motors. This includes trucks, b-bodies, and vans.
