PI Head Porting Project

[SiK98GT]

Well Since my 4.9 is in pieces i decided to up the anty and port some PI heads
Here is what i got done yesterday

One port Down. Now to polish it

All the material Taken out remember all that is done is 1 intake port

Update 1 Intake side Down :evil: now just to do the other intake side, then polish them both and start on exhaust

Been Really Busy so here is a Long Over Due Update:
Got Back to work on these things today. Did a good 5 hours of polishing the intake side will be done tomorrow, then on to the Exhaust side and combustion chambers, All i can say is this thing will put down some SICK numbers. A guy with a similar set up made 403 on a engine dyno with smaller heads less compression and milder cams. Needless to say this mother ****** will be a beast

Combustion chambers before, Note all the sharp edges and emissions bumps

And after all nice and smooth Note the fact that we removed the emissions bumps this will lower the combression by about .5 but it will yeild a better burn

Anyways I have Also Ordered my 9.5CC Dish Probe pistons and, matching cleavite rings. The block crank and rods are also back from the machine shop. I will have pics of it all soon. The cams have also been ordered. In the next couple days i will have more progress pics on the heads and pics of the rotating assembly

Lookey what i got today. So nice probe pistons. I went down to 10.5:1 compression for streetability but that is the only compromise i have made. Next week when i go to LA to start assembling everything i will take a TON of pics.
