It begins again - 512 Stroker

Can power be made with iron heads? yes, clearly it can.

But...money invested, reparability and drivability needs to be taken into consideration.

I had IQ do a set of performer RPM heads for me along with deep ported intake and a solid roller. I know what went into that money wise, what the flow numbers are and what the engine ultimately produced and where and how it produced it.

I'm not sure it was even possible with iron and if it was, the cost would be substantially higher without a doubt.
