alright...ive gotta bad ticking from my engine when i accelerate. so...i can tell its an exhaust leak..especially when i can smell the fumes in my car with the windows up and the fact that there are manifold gaskets on my car, not header gaskets. i have edelbrock headers....but....what i need 2 know is what is our port size? i saw mr gasket gaskets that were sm bk chevy 2??-4?? and the port size was 1.44 by 1.55. something like that. the others were1.30 by 1.36. u guys know what a port size is on a 305 tbi? stock heads...

 

Man when I had the 305 in my car I was using just the 1.45-1.55 gaskets and they worked great. I used to put rtv around the gaskets at the sealing surfaces and they worked a lot better.

 

good, i guess i will go with them unless anyone else knows of something different. am i wrong about those exhaust manifold gaskets being there? they shouldnt be right? it should be onepiece header gaskets right? thanx alot

 

When you swap out those gaskets be sure to check the bolts few days later for any loose ones.

 

Right on good advice. I forgot to mention that but definitely check the bolts. They tend to rattle loose sometimes. Escpecially if they are headers.
