hey guys will this cause hot spotting and pre ignition ?
would you run this ?

alanwoodieman · 11-10-2011, 09:04 AM

NO would not

David J · 11-10-2011, 09:15 AM

I've seen worse used . The pitted chamber will cc a little more than the others but once it carbons up that won't be as much of an issue . Are these rare or something ? Why not replace it ? Anyways you have a judgement call on your hands here . I personally would throw it out but I have plenty heads .

f1builder · 11-10-2011, 10:52 AM

i don't see a performance issue with using them.

Gumpy · 11-10-2011, 10:56 AM

Yes

if you are runing a stock eng it will run fine

You will never know what it looks like when in operation. It looks like it might be an EAB head and won't be a problem.

Looks like they've been planed a massive amount. Check the piston and valve to head clearance. Probably find there is contact and they'll need to be clearanced anyway. Then you'll want to find some better candidates. Brian

alanwoodieman · 11-10-2011, 12:51 PM

what heads are they? EAB-8RT-8CM-? I have a few extra on the shelf if you need one.

elwood · 11-10-2011, 12:54 PM

there EAB heads, and yes i could use one alan,

Russ/40 · 11-10-2011, 01:40 PM

Running it you would never know the difference. But, as easy as heads are to find, I'd replace it. JMHO

alanwoodieman · 11-13-2011, 10:50 PM

finally got to the parts barn today, don't have any EAB, just a couple of 8BA pass side, I 8RT drivers side, and a bunch of A heads, including one that is suppossed to be for a 42 "A" engine. Sorry

Walt Dupont--Me. · 11-14-2011, 08:36 AM

Elwood, the area above the pistons look pretty small, I'll bet the pistons will hit the heads. Walt

elwood · 11-14-2011, 01:20 PM

Hi Walt, these are the heads that came off this engine, its all EAB, I even found a EAB stamp on the crank.
Iv still got the heads off my 8CM, so iv cleaned them up and am gonna run them on this engine.
Im gonna put the cam Pete ground for me in it also, and plan on claying it all for clearance checks.
Thanks for the input, I always like hearing from you.

Walt Dupont--Me. · 11-14-2011, 01:54 PM

Those Merc heads are awfull big. I'd use the EAB,s if I could. Walt

elwood · 11-14-2011, 08:21 PM

would you use them pitted up EAB headsWalt ?
look at the pictures again please, that one combustion chamber is ugly.

elwood · 11-14-2011, 08:24 PM

could i get the 8CM heads milled 30 or 40 thousands ? to lower the cc,s and raise compression

jack orchard · 11-14-2011, 08:34 PM

just wondering-what the difference is between EAB and 8CM in cubic centimeters. how much lower would the compression ratio be?
