A friend of mine has a set of slightly used Vortec truck heads that he's willing to give me. I can only talk the wife into a tiny bit of our budget for mods (warning to all single guys - get married, and this WILL happen to you!). Is this a doable mod, is it worth it, and what all will need to be changed? I know the intake will have to be changed, will I need to get a new cam? Rockers? Anybody done this before and can you tell me what effect it had?

 

DB,

What Vortec angine are they from?

First of all, Vader, thank you for replying. The heads are from a 1997 K1500 and they're 350 heads.

Second: I just did what I should have done in the first place, and conducted a search of posts to see what I could find out about this swap. I found about 1,000,000,000,000,000 posts on the TBI board that will probably tell me just about everything I need to know. Things like: I have to mill the heads .045 in order to keep the 305's compression up to snuff, I will need to use a Vortec specific manifold (which I already knew) with a TBI spacer (which I didn't know). I have even seen lists of mods people have done to accompany the installation of L31 heads (as I now know they're called) and what it did for them.

In closing, let me just say this. I have an ASE Master Certification which I obviously got during my "idiot savant" moments, because I sure have not done myself proud with this post. I deserve any, and all, flames you thirdgenners care to send my way. That's all I have to say about that.
