With the temps changing from the steel block to the alum heads they expand and contract at different times, cheap gaskets will start to leak faster. I have been told just to find a good set of vortec heads from later model and have some work done to them. Can be cheaper and better performance.

Posted By: LeadFootedRacer On: 11-23-2007 @ 16:40:21 Reply | Top | Edit depending on your intake, depends on what your looking for. what heads are you looking for? heads for the 355 or your 305? my 305 79 caprice wagon had 60cc heads and thats a pretty small chamber. you'd gain compression that way. --  Posted By: Remdog On: 11-23-2007 @ 22:56:46 Reply | Top | Edit u can get pro comp aluminum heads off ebay dirt cheap Posted By: camaro91 On: 11-24-2007 @ 01:59:16 Reply | Top | Edit i'm lookin for 355 heads... and ya i was lookin at pro comp and patriot heads... i got a friend with patiot heads and they seem to be workin pretty good for him -- '91 RS, 305 tbi, auto, flowmaster american thunder big plans! 355 lookin for 11's! Posted By: LeadFootedRacer On: 11-24-2007 @ 02:27:31 Reply | Top | Edit oh. sorry. good luck on your searching. i have been planning a 350 build for my car for a long time, and still can't decide on heads -- Posted By: camaro91 On: 12-03-2007 @ 12:28:39 Reply | Top | Edit so i looked around i think i'm gonna pick up some trickflow heads. 195cc runners and 64cc combustion chamber. gonna run me between $1200-1400 -- '91 RS, 305 tbi, auto, flowmaster american thunder big plans! 355 lookin for 11's!
