Default Trick Flow 225 Heads On LS1?

There is very little information out there about this.. What will happen when putting on Trick Flow 225 4" bore heads on an LS1? I know that the 243's bolt right up just fine, is it any different for the Trick Flow 225 heads? How will this effect compression?

Thank you in advance!

I was under the impression that that they will fit fine, but there are better choices on a stock cube LS1

Not sure what the valve size is on a 225 but you may or may not need to be concerned about valve shrouding

I put some as cast TF 220's on a stock internal cammed LS1 T/A a couple years ago with a FAST 92 and that son of bitch went out and ran 6.9's

I think it even popped off a 6.7x if i'm not mistaken and that was with a 1.5x 60ft. And it was not a monster cam either. Car had no a/c and tubular front suspension. It was a really good simple combo that ran it's *** off. It had cheapy long tubes and stock rockers, it was not a high budget max effort build but it kinda ran like one.

They will work fine. Make sure to use the correct pushrods! You can toss a good sized cam at them and have a good combo.

Have you purchased the heads yet?
