No there 317s from an lq4 they flow about the same as 243s but have bigger combustion chambers that's why I milled them to bump up the compression

I'm not really to sure on the compression it all depends on what type of gasket you use stock their 9:5:1 so with the milling and a thinner head gasket they should put you around 10:1 you should always measure pushrod length
