In the head, that way the heat was kept off of the gasket & as far away from the carb as possible but actually now that you mention it I believe either would suffice. live every 24 hour block of time like it's your last day on earth

So I cut that part out with some snips and used some rtv to them hold onto the head while I put the intake with the regular 360 gaskets on. About a year later I had the intake off cause I broke a push rod and noticed that the tin had burned through in that time. When I put it back together I didn't bother trying to block it because I figured whatever I used would burn though again anyways, or be too thick and interfere with the intake sealing right. The best way I would think would be to weld up the crossover itself in the intake as said above.

The reason I want to block the crossover is because I can hear gas bubbling in the fuel bowls after I shut it off. I am also going to install the valley tray I just ordered (I used to have one and that kept the intake nice and cool). Since I dont need the chock well, and the paint is starting to blacken near the heads at the crossover, I figured it wouldnt hurt to block em. 5005413-SDC10286sm.JPG (264 downloads)

That's the funniest retort I've seen in a while, even more so considering the guy's name is Bill MeLater. Parts I seek: driver doorpanel, 65 Sport Fury, prefer black, needs to be 7-8 on 10 scale, might buy set 16" x 6" Dodge truck wheel(s), from early 70s?, takes 9" dogdish - need for a research job so cheaper is better. 69-73 C-body caliper brackets and/or splashields Send a PM.

Simply mix up enough to fill the hole, pour it in, tape off the face of the ontake and set the intake so that the tape in down, gravity does the rest. If you find you didn't quite mix up enough it's easy to add more later. They say there are no such thing as a stupid question. They say there is always the exception that proves the rule. Don't be the exception.
