im getting a 350 tpi engine soon possibly and was wondering if i put the heads off of my lo3 onto the 350 if it would help? i plan on converting the tpi motor to tbi because the wiring harness is all jacked up

dude keep the tpi 350 heads, stock l03 heads just suck unless u do some porting etc.

I would keep the 083 heads too.

ok it was just a question cuz some people said the 305 heads would be good. just wondering.

They prolly said that cuz 305 heads have smaller combustion chambers and it would give u bigger comp. ratio .

TBI heads are very poor when it comes to the airflow department. I think they only flow around 180 CFM. They have a swirl ramp in the intake that helps boost torque. Problem is that its large, and restricts airflow. The heads are essentially useless when it comes to performance applications. They can be made to flow OK, but aren't worth the effort unless your purposefully experimenting.
