I found a good deal on a lq9 but he has 241 heads with it. Do they flow as good as the 317? I know they would bump compression up and I don't know how much or if it would be a good idea anyways considerings it's a lq9 high compression. The cam is a 216/224 also. What do yall think?

the 241s arent as good as the 317s. the rise in compression wouldnt be much probably be around 10.3

if the 241s have the same combustion chamber size as the 243s, which i think they do. the compression ratio will now be about 11:1

11:1 is about as high as you can go on 93 octane safely

i think 317s flow a little better than the 241s

that is also a nice cam, just a bit on the small side for a hi-comp 6.0

The chamber size on 241s is 66.67 and it's 64.45 on 243s

So should I try to sell the 241s and buy 317 or should I just leave them on there?

I would feel more comfortable with the 317's, they do flow better, and just mill the 317's to get the compression up, milling can be done for very cheap, less than $100,
