Stick with the 241s or go 243 heads?
So long story short I blew my forged 348 up a few months ago. I'm building another ls1 now. I need to put some money in the heads due to them being slightly damaged. Nothing major.
should I switch it up? My 241s are ported but I didn't get any flow numbers when I bought them. I was thinking of buying the texas speed ported 243 heads.
Would I really see much of a power gain on a boosted set up? I made 675whp with the 241s and then ran out of turbo.

My other option would be put a couple hundred into my current 241s and save alittle cash. I guess my question would be are 317 or 243 heads that much better than ported 241s? Will I really see an increase in power?

Its a matter of lowered compression more than anything, the 317s drop you about a half point. With FI you dont need to have awesome flowing heads to make gobs of power either
