    Have the heads been used? If so how many miles are on them?

    I probably put 1,500 miles on them. However, I forgot to state that one spark plug hole is partially stripped. I dont know what it costs to fix it. Other than that, the heads are in great shape. I will drop the price to $500.

    The chambers are 64cc,,, I believe that my CR with these heads on my LS1 engine netted 10.5 CR. There is carbon build up in the chambers which is expected.

    I blew my LS1 engine at a Porsche driver school event about 2 months ago. The #8 piston simply shattered. I have no idea why this happened. I am in the process of building either a 416 L92 or LSX 440 shortblock. In doing so, I will buy new heads.

    The valve sizes are 2.00"/1.55".. As I understand it, these 243 casting are LS6 heads. And, according to Patriot performance, these heads flow 300 CFM at 0.600" valve lift.
