I was wondering if there was a way i could possibly clean the inside of the plenuim on my 2.5L maybe with a honning brush? or may be a easier way i know i looked down it when i had it off last and wow it was nasty looking and not just build up but the inside was all pitty like how can i go about smoothing it out? thanx

For the build up, if you remove it from the motor, you can spray some carb cleaner into it. As for the pitting, that's just how the cast set. You can try to smoothen it out, just be careful to keep it all even.

 

Get it extrude honed ...

 

where would i take it for that bv machine shop?

 

mostly motor builders ... they pump playdough with grit thru the plenum going progressively less agressive grits till it's got a mirror like finish ...

we port matched the upper/lower before the process...

 

Ok when it comes to all the port and polish stuff i know what it is but just how much does this usually cost to do the heads, and about what should i expect to pay for the intake? not wanting to do the 2.5L heads but the 3.0 heads whan i get the 3.0L swap in.

 

port and polish heads depends on the degree you want to go ... $300/$1000+++

I paid $150 for the extrudehoning on the intake .....
