I have my heads at the machine shop right now and was wanting to mill my heads .030" or down to 61cc to achieve 11.0:1 on a LS6. I mentioned it to my machinist and he brought up the issue of PTV and also some cams might not work with my heads milled that much..

Can I get some examples from you guys that have milled your 243s and aren't having any clearance issues and what cam you guys are running with the heads milled?

I'd also like to know if my cam of choice, SNS TorqueMax Stage 3 235/243 .62x"/.62x" LSA 111+2, would still work with .030" milled off my heads? If not, then what cam would you guys suggest? This will be a weekend warrior type of car so I do not necessarily need a "smallish" type cam for daily driving. If my cam of choice doesn't work, I'd like to get something just as gnarly of a cam that would work. Badass lope, pulls hard through the rpm range but mainly looking for more top end power as my car will be a highway/street puller.

Any suggestions would be awesome guys! Thanks!
Nate.

.030" would be what we mill for a 228R.

235/243 will hit for sure on stock short block and .030" milled.

I've read about the 228r cam and hear great result about it but I'd like something a little more aggressive since my project will not be a DD. Would the TSP 233/239 cam work if my heads get milled .030"? I'm trying to debate whether I should mill the heads and run a slightly smaller cam or leave the heads stock (port them in the future) and run a bigger cam? Can't make up my mind.

No, Max at .030" is 228R. If you want to get more aggressive with the cam, you have to get less aggressive with the milling.

Okay I understand now. Damn. I don't have the $$ to port my heads right away but I do have the $$ to mill them to bump my compression ratio but I also don't want a small cam. I guess ill leave my 243s stock until I can port them and will still go with my first cam of choice.

You can still mill the heads. Just don't go so far with it.

.030" = 228R
.020" = TQR2/3
.010" = MS3/4

These are rough measurements. Please call for exact specs before milling or just send your heads to us and tell us what cam you want. We will do the rest!

I will definitely give you guys a call. How much money would I be looking at to spend if I sent you guys my heads and picked out a cam to be had with them? I really wanted to mill them to get 11:1 CR. Would milling them any less than that still benefit me? Say I only milled them .10" or .020", would I still benefit with a pretty decent sized cam?

Before you mill the heads talk to advanced induction about welding up the chambers.they do it on 241,317,243 castings and still have good ptv Clearance

Welding up the chambers? I've never heard of that method before.. Maybe I don't know enough yet lol.

It makes the chamber smaller without milling the heads

You are correct about the sns stage 3 cam. I had my heads milled .025" and I'm running .040" cometics. I had to fly cut .060" to get exhaust ptv clearance back to .100"

How do you like your cam buddy? The SNS TorqueMax Stage 3 was my first choice and I'm still super interested in it but don't have enough feedback or input on it to know enough about it other than what Tick's website says about it.

Flycut. Mill to what you want and run the cam you want.

It's easy.

Good work Jake props.

Sorry bud, I won't be able to tell you till spring. I need to get it back to Speed Inc to get the tune tweeked.

I completely agree. I went from a what most people would consider a daily driver cam to the setup in my sig. Don't do it twice fella's. Go with your gut and pick the cam/setup you want. Jake, those pics look all too familiar. Here's a shot of mine...

I don't know enough to flycut lol. This is my first build and I would like to keep it simple as possible. I only wanted to mill the heads to bump to 11:1 just to get a few extra horses but I can live without milling them. I want a badass cam, don't care about DD cams since my project won't be a DD so I'd like a pretty decent sized cam but then that also means I need to port my heads which I'm planning on doing as well but would a big cam still put down some good gains on stock 243s?

Oh wow dude! Thank you for posting that link. I think that just set it off for me. If I saw the numbers correctly (dyno graph pic was to small) but at 427rwhp with only SNS Stage 3, UD pulley, headers, and a fast 92/92, that's amazing! I probably won't get a fast intake; ill just port my ls6 intake. I've heard controversy over porting the ls6 intake though. I hear it doesn't do much for you over stock. Yeah that pretty much set it off for me. SNS Stage 3 it is. I was also contemplating the MS3 or TSP 233/239. I'm glad I got to see that dyno graph with stock 243s cause that was really crucial for me since I won't be porting my heads until the future. I was worried I wouldn't benefit much from a big cam without porting my heads but that graph proved otherwise. Thanks for sharing that!

LS6 intake (unported), ported 243s milled .030, TSP 233/239 cam, LTs. 430/373 to the rear with .100/.110 intake/exhaust PTV clearance.

EDIT- that's on 10.75:1 compression and the exhaust was just headers/y-pipe. Didn't have the cat back before the dynotune.
