Favorite 350 Heads for 1996 LT1?

[Streetbu]

Got a link to those springs? I assume you're talking LS6 springs, they're over $70 last I checked.

Yeah, they've gone up $30 since I bought them 4 years ago... :/

If the truck is a 1996 then the motor will be a 880 block WITH vortic heads. Unless some one changed the motor or heads. These will be 062 or 906 casting in the heads. On the ends will be a saw tooth for the 062s and the 906s will have a half moon circle. If the heads have a half square then you have a set of 305 heads I think the casting is 060. These are of no use for making power of any kind. Also vortec will have 4 bolts only on each side of the intake going straight down. Not sure what heads you have.

No it's from a 1996 Chevy 2500 5.7 and the heads definitely aren't Vortec, which is why we are adding them. If someone just said "here, these are the Vortec heads you want for a Gen1 engine" I'd buy them.

StreetBu already messaged me the perfect springs and retainers to get for the heads.

Then you either don't have a 96 or someone put the older, crappier heads on. Does the block have the bypass port in it?

You're 100% correct.
Mechanic confirmed it's a 1995.
Which did not come with Vortec heads. One year made all the difference.

Sum-K00042 is the CAM we are putting in.
