head gasket gone again

well i replaced the head gasket on my 69 camaro about 200miles ago if that i used feelpro and thats what it had before it went out..well today they bust out again compresion is 11:1 should i use copper head gaskets are they stronger? i also have aluminum heads if it matters...

Worse case scenario, the gasket mounting surface is not even and would have to be trued back up. Very important when cleaning an aluminum gasket surface, to use the proper gasket cleaner. Basic scotch pads are too abrasive as is sand paper. Simple fixes would be making sure the gasket surface is completely clean and the head bolted back down with the proper torque specs and bolt sequence.

yah what he said, if your engine has ever been overheated theres a good chance that you warped that head. Or if its been severely over heated the deck of the block could be warped.

yeah i had the head trued back up last time yeah the surface was clean and everything...i over heated to 240 i dont know if thats too much ..but im gonna have the motor out this time and have themshave the block down see if it helps or sumthing any more sugestions..thanx guys

IF you use the felpro gaskets, make sure to use copper coat. What that does is seals on both sides. I used it to rebuild drag racing motors. I use copper head gaskets on my pro mod motor but do not like to use them on street motors. You should make your tourque pattern in a circle. Start in the middle and go right then up then left back done to middle. What size motor is it?

its a chevy 350 bored over 30 400crank..yeah i do use the circle torque pattern..i used the regular feel pro # fpp-1004 wich ones would u guys recomend to use...any sugestions why they went out? maybe gaskets aint strong enuff?
