Re: chevy 307 heads
Put 305 heads on there, it will increase your compression and give you some horsepower!!![img]/wwwthreads_images/icons/smile.gif[/img]
I don't know why the 350 head would make it run hot, but maybe they were warped or something?
Put the 305 heads on, and you will thank me later! [img]/wwwthreads_images/icons/wink.gif[/img]
Dave is right, throw away those rubber intake ends and use silicon! Even if you do get them on right and all sealed up, sometimes they still get sucked in later![img]/wwwthreads_images/icons/mad.gif[/img]
