i got a 302 with comp 274 cam 2 inch h pipe with i chamber flows.
when i get in the gas hard it starts to pop like an old chevy truck ( does that make sense?) is it because i have a lifter on the exhaust side of number 3 cylinder that is collapsed? imean will it collapse so bad that the exhaust valve wont open like it should and build up in the combustion chamber? please help if you you know anything that could be wrong
