blue smoke on acceleration , dramatic increase

Others may disagree but i had many head gasket failures , in 97 i started to use Felpro 1008's and i never had a failure since and thats with a 530 hp stroker plus a 100 shot and a good few 340's . i was using Detroit head gaskets before that and would last less than one season .
Yeah, Detroit's are the softer graphite type.
Makes sense!
