292 12 port sbc heads

What do you think about the whole "cutting and welding of two 350 heads to make a single 292 head?" I have two spare 350 heads that have 1.95 and 1.55 valves in them already? I also have two stock heads for a 4.3L v6 that are identical to the v8 heads, just minus two cylinders... I'm confident in my welding, but...
Opinions?

 

Get a hold of Mike Kirby at Sissels in West covina CA.He was making some pretty cool aluminum heads for the chevy 6.I have his number here somewhere if you cant find it online

 

This has been done before.

Bruce Sizemore is the guy back in the day that did this to a Ford 300 6 cyl. truck engine with Cleveland head conversion.

Have a read of the story on this link.

I know I have a magazine article on this from Popular Hot Rodding back in the 70's devoted to the build of kind. I will try and dig it out. Was a very effective engine once sorted. One many drag racing events and records.

 

I know leo santucci made this setup and I ordered his book It should be here by early next week...

 

You need to get a copy of Leo Santucci's book.

 

The big reason to do the sbc heads is ...options....opens up lots of flow tech.....far..far...above what you can do with a stock head.....there are some real great aluminim heads out ther for the six....but think of the options ya have with the sbc set up.......lots of work ...for sure....I drive Leos car......and I can tell ya...that set up peeeeels

 

i have done a few of the heads many years ago. i am working on cutting a pair of zz4 heads now.

 

old school ....dig the sectioned vette valve cover.
