Slover ported Bowtie heads with some Charlie porting vs. Old Chevelle Bowtie heads.

Hi Charlie. Thank you for the comparison of the two heads. The exhaust was really interesting. Not knocking anyone but a smaller port with more flow sounds better to me. Andrew

Michael Slover always does a fantastic job.

Yes they appear to be angle milled . being the case will that
significantly change the. Short side for the intake and allow you to lay it back more ??

[@servediocylinderheads]

Nope, that is not accurate. The casting does not change. Just the angle in reference to block deck. It can change airflow.

Good info, I looked them up. 1.6 valve, 70 cc exhaust port, flow 205 cfm @ .8". Thanks

👍💪

[@davidresar8256]

On the exhaust, what could you fill the port with to raise the floor and get the flow back?

[@servediocylinderheads]

Weld

[@servediocylinderheads]

I will work with the remaining metal and airspeeds and see if I can make it better. Thanks

Would you happen to know which bowtie blocks could be used as a wet sump?
