Alum TPI head on LO3

I can pick up some aluminim heads off of a tpi motors for $100. Would it be worth me time and effort to put them on my LO3?

uhm, nope, you should sell them to me

Just kidding.

Yes, they would be WELL worth your effort, they flow much better then the good for nothing swirl ports, they knock off a good chunk of weight also.

go for it! Thats an amazing deal.

I told the guy I would take them, just havent heard back. I am going to get a lt1 cam and a set of headers, they are probably going to get ported and a valve job.

Dont forget you'll need to elongate the middle four holes in your intake manifold to match up with the heads older style bolt holes. Also, you'll need to drill and tap a new hole on the passenger head for your accessories. Last, this heads have no EGR port, so that system will not work anymore.
