Yea, they are ported NPI heads.

 

That's what my engine bays gonna look like REALLY soon !!!

Thats nuts though! All with NPI heads...i

 

Once fully ported and running bigger cams and a better intake, the difference between npi and PI heads is really insignificant.

Edit: maybe not insignificant, but certainly much less of a difference when all the major problems with the NPI top end are addressed.

 

Yea nick Posted about that car, back when it was running a 12.1

awesome car for sure, id also like to note that car has Stage 3 Cams and 4v Pistons.

 

little do people know, that worked non PI heads will flow their ***** off

 

I believe it. Lol and yea, it's running high compression, but who would be that uneducated to build a purpose built n/a or nitrous motor low compression? And they are MHS stage 3.5 n/a cams I believe, not just 3's.

 

I seriously cannot imagine how annoying it must be to drive 4.56 gears on the street on a 2v.

 

I don't think it would be too much worse than 4.10's or 4.30's. With a built motor like that, I highly doubt the guy cares about fuel economy.

 

I don't give a rats rectum about fuel economy either, I just meant it as an annoyance of having to be in third gear by the time you leave an intersection practically.

 

I guess one benefit about 4.56's is you would really never have to use 1st gear if you didn't want to!
