tbi head flow, 193 iron LO5 head: 178 intake; 146 exh
tpi head flow, 083 iron L98 head: 194 intake; 106 exh
tpi 305 head flow, 081 iron head: 195 intake; 110 exh
tbi 305 head flow, 187 iron LO3 head: 165 intake; 140 exh
Im not saying go out and rebuild a set of tbi heads over others, but for their purpose they work well. The tiny factory tbi cams and low compression really hurt those engines. I do like the l98 aluminum vette heads, good head for the price. But like mentioned above, if buying new/remained the the tbi long blocks are well priced and are roller blocks.
