What is the diff.
I have a set of heads off my 99TA. The casting is 853. What is the difference in these and the 241s?

The 853 doesn't flow as well as the 241. The 241's were on 01 & 02's.

different casting 241's should be slightly smoother, not enough for a head swap though.

any chance of getting a sticky on oem heads, specs, advantages/disadvantages, and posibilities of porting?
I don't know if its too much to ask of the mods, but I know it would really help a lot of us out.
I've learned more than I ever thought I could here on the site, you all do a great job!
