Any COMPETENT automotive machine shop should be able to do this. It's done all the time to true up the surface.

 

Oh yeah! My custom speced PatG cam. Everything else I'm doing is really just a supporting mod for this one part! I dropped the heads off this afternoon to be decked. I'll have them back tomorrow or Wednesday.



PAC .660 dual springs with titanium retainers.

 

Which 92mm throttle bodies would you recommend?

Heinmo - $55
Jegs - $145
WARR - $145
Holley Sniper - $175

 

The WARR seems to be recommended on here a lot lately. I've read bad reviews about the Holley Sniper, so I'd stay away from that one. I picked up a WARR 92mm myself for my Fast 90 intake.

Also, I would say spend the money on the NW, but people have had issues with those that the WARR fixed which is why I just spent a lot less on the WARR and will mess with it to get it right if need be.

 

The heads are back. I installed the valves in one cylinder of each head.

Combustion Chamber - 63.5-64cc (I was expecting a little less than that with .008"-.010" taken off)
Intake Runners - 212cc
Exhaust Runners - 78cc

I need to clean them up spotless and install the new seals and springs. Not tonight though.

 

Which head gasket are you planning on using?

 

Cometic .040".

 

What compression ratio are you shooting for?

 

I was hoping for 11:1 or better. I'm not sure this will get me there.

 

You'll have to run the numbers to verify but if my memory serves me right .040 Cometics and a light milling like that should have you damn near 11:1. If you have adequate PTV clearance and if the shop doesn't charge an arm and a leg to mill, I may be inclined to mill em some more but honestly I wouldn't sweat it too much unless the DCR is lower than optimal for the cam you're running.

 

I used an online calculator and get 11.05-11.12 with a CC of 63.5-64cc.

That looks like a good compression calculator, in that it figures in HG bore diameter. Summit's does not.
Anyway, it looks like you made your compression goal!

 

What are you guys running for a catch can? I can't see spending $250 on a Mighty Mouse. FYI, I am converting a LS6 PCV valley plate.

 

The heads are ready to bolt onto the car.

 

Impressive work from how they looked before.

 

 

You must have done this before? I wish I would have attempted cleaning up some beat up looking ls6 heads as opposed to buying some already worked ones off this site and probably spending a little too much. I just wanted something I could bolt on a go for a while and later send off for porting/vj.

 

I did a set about 10 years ago for my truck. I have about $700 and 20 hours of labor in a $1,700 set of heads. I can't stand to pay someone else to do what I can do. Plus, there's a lot more satisfaction in having done it yourself.

 

I definitely get you on that. I am somewhat new to modding cars, but I am going to tackle the h/c/i + clutch install on my own eventually once I save up for everything. I just wouldn't have any clue on how to port cylinder heads on my own. I guess I need to read up on that.

 

Are you still planning on a DLS2 or FAST intake OP?
