need a new head help with options..

[jmorando05]

So i was leaking water into the cylinder and then into the oil long story short there is a hairline crack by the one valve on the head. heads for the 350 magnum are not cheap new so does anyone know of a scarp yard or where i can get on used and have it rebuilt with my other or even a set of remanufactured heads at a decent price.. cast # is 14101081 and engine serial is 0F605596

Are you sure about that casting number?

Use the IMPATIENT hyperlink.

According to this, you are using 305 heads.

Check LanierMarine.com outside of Atlanta. They're a huge boat salvage yard--and a source for parts. Otherwise, EBayMotors.Com has about everything listed in their parts. If you'll go to BoatTraders.com, you may can spot other boat salvage yards.

Did you look at the web page?
Match the casting number from the block to the chart, you should find out what's in the hull.
Next, look at the chart, ANY heads compatible with the block will work.
The chart shows there are no marine cylinder heads listed.
The only thing different between a marine cylinder head , an a automotive cylinder head is where the head sits when it's in operation.

I'm just guessing, post number three sounds like a good alternative.

but true vortec heads start in '96 im worried about fitment issues and most places wont take these as a core for a vortec head..

Re: need a new head help with options..

I bought a set of vortec heads online. New castings, new everything. They don't want your castings. Google cylinder head. Place was out of alabama. Cost me $3oo apeice. The pricey peice is the marine manifold for TBI.
