My heads
Are my heads worth keeping. Their casting number is 3927185 and the symbol on the head by the casting number looks like a L. Thanks

From Mortec:
3927185....69-76...307/327/350..70cc chambers
Total garbage. 2-bbl heads.
Put them in your cast iron recycle bin.

Re: My heads
I had a feeling that those heads were worthless. The problem is that I cannot afford new heads right now, I have about a $300 budget, what could I do to get more performance using the heads I currently have?

Re: My heads
Snag some heads off a mid '80s 305 at the JY. Do some port work and have fun.
