Any value in a used set of merlin iron heads? I-043 casting #. 95. Those are the only #'s i could find. I believe they are a 320's. Been stripped down and checked. 1 head is good. 1 head is cracked in 2 places. Was told its fixable but i bought a new set of aluminum heads.


Figured id check before i scrapped em.

sell the 1 for a couple hundred bucks.wheres the other one cracked?

Probably enough weight to hold a float ball for a small boat.....

Sell the bad head on CL. Depending on where the crack is, someone may want to buy it and fix it. I had a guy tell me that guys that run alcohol motors don't care if the heads are cracked, because they don't run coolant.

1 crack was there before and had been repaired. Didnt appear to be leaking but the builder flagged it. The other crack was right by one of the valves. Again it didnt appear to be leaking as i never had any signs of water in oil or anything. Motor was still running good but lost warm. Oil psi at idle so i pulled it. Ill throw em on craigslist and see what happens. Think $200 is fair for both em? Not trying to get rich and dont wanna try to screw anyone either

Save yourself the headache and scrap them.

Cracked btwn the int and exh?

Had a bunch of 80's and early 90's GM castings crack there.

Sell them on racingjunk.com Some of the bracket racers like them alot.

Thanks for the replies. I dont remember which valve hole had the crack but ill check it out tonight. Honestly i just wanna out of my way but figured i see if i could get anymore then just scraping them. Ill post em on craigslist and racing junk amd if no interest they will get scraped with some other crap
