You don't have a 99 with stock heads that are 241s.

That's about as realistic as the guys that ~swear~ their cars came with 243s. It's just not true

Hate to say it buddy but yes your wrong.

No 99 came with a 241 casting ls1 head. They weren't even out man. Might wanna know your car a bit better before coming to the table with that...lol.

Oh and yes 97-98 Ls1 received the 806 Castings. What are you thinking?

Haha...good try on putting me down though man. It's ok nobody is perfect...

Good point here...If you were mid year to late year you could have the next phase of castings.

This does not apply to any 99's whatsoever though...Mid to late 99's received at most early 00 heads which were still 853's.

It's a time bomb with those darned 853 castings
