junkyard heads

[tcfco2005]

im thinking about getting some junkyard vortec heads and i was wondering what cars or trucks came with these heads. and can i put 350 heads on a 305.?

Yeah someone hurry up and answer his question. I need to know too!!

i do not know what car has the heads but i know that the 350 heads wont fit on the 305, they may bolt up but because of the different bores i wouldnt suggest it

??? bigger runners and thats a bad thing ???? but what? sorry im a 350 fan but i hear of 305 heads on 350 for smaller combution or is that what you are steering them away from??? make sure there the same cc or smaller (highr compresion ) thasn your previos

the vortecs you want are the 062 castings. these can be found on 1996-2000 CK pickup trucks, tahoes, suburbans, and the GMC counterparts.

Yes these heads can be used on a 305, the small valves dont have a problem with the smaller 305 bore, but you wont want to upgrade to 2.02/1.60 valves for clearance issues. some people machine the heads down to a smaller chamber of roughly 58cc's to run with the lower displacement. Other than that youll have to get a dedicated Vortec manifold, and an EGR adaptor tube because the vortec heads dont have egr ports. SDPC can hook you up with all that youll need.

[tcfco2005]

[stephenp]

and any way of telling the chamber volume on them???? any specific head casts???
and what ones besides the castles come with the 2.02 stock??? how about heads that just have springs that will take a good lift
hell just good heads lol
or just good head would work
