i dont know if the heads were resurfaced. the seller said he degreed the cam in at 106. i checked the cylinder pressure numbers and they were all right around 160 psi on my gage. i just know the intake, carb, and distr were all running fine on my motor before and theyre not working on this motor so it has to be the longblock. im just looking for ideas before i take it out of the car cuz my place sux to work on cars so i need to know what im dealing with before i get started. plus with school I dont have unlimited time.
