Since I'm yanking the heads off of my 99 LS1 heads anyways.. And there's a guy selling stock 241 heads locally. Do you guys think its worth it for me to swap heads, I know the 241 heads flow a bit better?
I'm doing a cam swap as well.

 

+1

 

Oh and I would be rebuidling the 853's anyways... so either heads will get a working over. He wants $150.00 obo for the heads.

 

I'd probably save the money and find a nice set of 243s at the least.
