pbguns

My motor wont start it turs over gets gas gets spark has combustion but wont start. Because i changed the heads the old spark plugs dont sit down it the cylinder far enought to ignite in the cylinder. Has anybody ever ran into this if so tell me if the spark plugs fixed your problem.

Hadnt really run into it but i could believe it if your using stock reach plugs on a head with .750 thread length.

i forget what autolite size im using, im pretty sure its for the stock heads on my 95. i got edelbrock rpm heads, would that cause a problem with my heads?

Edelbrock tells you what plugs to use, They are much longer and have a compression ring on them, and Autolite irridium tips are the ones to use.
