305 vortec heads
i have a set of 305 vortec heads that i had bought and put on my 305 but i spun a bearing so instead of rebuilding the 305 i'm getting a 350.
heads are in good shape didn't smoke, $300/bo
i'll get pictures and numbers up soon

Re: 305 vortec heads
yes they will work with tpi, but not with the stock base. vortec heads have a different bolt pattern, so you would need to buy a new lower intake. like this...

which at a little under $500 is kinda pricey.

Re: 305 vortec heads
Can you post a pic with a clearer shot of the casting number? It's not clear in the other pics, but it looks like it might be the 350's casting number, not the 305's.

Re: 305 vortec heads
The vortec truck heads (906 062)have the ideal heart shaped chambers. Those chambersabove, although on a 305 vortec head ,are identical to all other run of the mill GM head.

Re: 305 vortec heads
Yeah you can buy a vortec intake for a carbed motor and also an adapter for the tbi unit that's what I did with my vortec 350

it's a little late tonight but I'll post the casting numbers tomorrow. I've been out of town all week working and haven't been able to do anything.
