Default Ported TBSS Intake Manifold on Stock L92's?

Found a ported TBSS intake manifold at a steal. Question is, what would be the flow comparison to L92 heads (stock)? Would I need to port the heads, would it hurt the flow due to conflicting volume area ? I know I would need a retune after install, I'm just trying to decide if its worth buying if I dont have any plans on porting my heads at the moment due to the fact they already flow well enough for me at the time being. Thoughts?

TBSS manifold will not work with L92 heads.....TBSS is for cathedral port heads and L92's are rectangular ports.

/\ What they said. Plus the L92 intake is pretty similar to the TBSS intake anyway; even if it did bolt up it wouldn't likely gain you any power.

You could port your stock intake. Just take it slow and put your grinder on low speed.

Remember playing with blocks in preschool and no matter how much you tried to stick the square block in the round hole it would never work? .. Pretty much the same concept
