317 heads

I have a chance to pick up a set of 317 heads from a 04 Denali 6.0 for $150. These heads worth the $150? The heads have 80k on them.

That's not a bad deal for low mileage 317's. They're going for about that to 250 where I'm from

I thought so too. I plan on only heads, cam, and intake but I am trying to find the best deals I can. Just looking to have a good weekend cruiser. Plans are a tr228 cam, 317/243/799 heads, whichever is can find the best deal on, and a LS6 intake. Car is a 2000 T/A M6. Just turned 73500 mi. Bought her in February for $5500. I think I made out pretty good on the deal.

If you're keeping it N/A, I'd go with the 243 or 799 heads.

I briefly thought about a turbo the other day but I think N/A is the way I'm going.

317s have the same ports as 243s and 799s, but bigger chambers. Like stated, they will drop your compression.

Well I would not over look 317s at a good price . The 243 has no real big flow advantage over the 317 especially if your going to port them, same basic port and runner design. Machine shop in my area charges $75 to mill up to .050 I would mill to say .030 and that put you in around approx. 67cc , which is Stock LS1 cr territory. So $150 for the heads and $75 to mill total $225.
