Will the TFS 220 as cast ls2 heads fit an LS1? I looked on the TFS website, and I noticed that the intake description is different; I belive for the LS2 it says cathedral. I guess what I'm getting at is if I bought the LS2 heads for my LS1, will they work without having to do anything to them? I have the LS6 intake for now, so I would want it to work with those heads. Any help will be greatly appriciated.

 

Email Trick Flow with the part # post it here. You just dont want heads made for a 4" bore vs a 346 stock LS1 bore.

 

I would get the LS1 heads. When I bought mine from TEA they told me they liked the LS1 chamber a little better. Mine are going on a 403 in a few days......

 

The reason I'm asking is because a guy is selling some TFS 220 heads on here and he said one head has the LS2 casting and the other has the LS1 casting. That just doesn't sound right to me, but I'm waiting on him to reply back. I really want a set of the TFS 220 as cast heads, so if you guys know anyone who has a used set for sale, him me up.
