As the title states, is there any benefit to me switching from 806 to 241 heads? Got a good deal available, and they are milled to bump compression. Thanks

Well, you would have to switch a couple things. For one the valve covers are different, center vs. perimeter. I think the coil brackets are too. Just get those 806's milled/ported/lapped and upgrade the valves and springs and you will have a lot more power. I bet you would see 35rwhp give or take 5rwhp.

yea man i did the same thing as you but ported them for almost 35 hrs...yea it worked a little but they maybe flow 20cfm more then stock....but as stated above by time you add the fluid bolts and gaskets it almost becomes a waste...
-241 heads brand new...200 shipped
-porting heads 35 hrs and a pain in the neck....tool to port....120
-head gaskets....140
-head bolts....50 per side...100
-so almost 550 for everything.....GAIN= maybe 25 rwhp
so i think if i would have just slaped some texas speed heads on her id have a nice set of proven heads that worked for more then a couple thousand miles...my head now cracked...lol

yup like i said, they can be made to be bad *** but imo your better off picking up a fresh set, and stock 243's would b a nice touch too...but with my experience my combo only did 11rwhp more then the ticks polluter car. i just look at the 35 hours i ported and all that for 11hp?

^^^trust me you are 100% correct brother...ive learned tons about head porting in the last few years, so much i decided to do the heads...lol but the heads did perform very well, way better then i had ever thought but i did make some booboos one of witch killed the heads. on the intake side, right head i ported thru the water jacket and welded it back together nobody in a million years would have been able to see it but that weld broke im guessing because the lack of power and antifreeze in my exhaust and not in my oil...
