<html><body>I used this on all the 100 heads that I assembled with a copper gasket and so far no problems from any of them. It goes on very nicely and, if the head and block is in good condition, should do the job.

<div dir="ltr">Hi Michael -
<div><br></div>
<div>Sounds to me the smart thing to do is put in a steel
head gasket because the head was rebuilt not that many miles
ago, so I might have a low spot there. The head is torqued
correctly so that's not it.</div>

blown gasket at the 3-4 bridge. My original head suffered
from erosion of the metal at the 1-2 bridge, allowing the gasket to
blow. I had it built up enough to work for a while but
eventually replaced the head with a DWR AL model. </div>

<div>My A90 just started running weird. So I took a
compression tester and I'm getting (note the A90 is lower
compression than the 100):<br><br>
1 - 135 psi<br>
2 - 135 psi</div>
<div>3 - 60 psi</div>
<div>4 - 60 psi</div>
<div><br></div>
<div>When I put the compression tester on number 3, I get blow back
through #4 spark plug port. Then when I put it on #4 I get
blow back through the #3 spark plug port.<br><br>
Seems to me it's just a blown head gasket.... am I correct?
as far as I'm aware, these heads usually crack between 2 & 3,
correct?</div>
