Streetmaster to Airgap

Jesus, this is still going?
I'm surprised you could even find a good set of 302 heads over here. I've used a ported set of "truck" 277 casting heads before with good results on a mild motor for a daily driver but if I was building a performance engine I would be looking to start with a better head. (The 277 heads look to be a better design than the 302 fwiw)
