Old School heads on a LT1
I just got done installing my GM 847 cam Now I need heads. I want heads that flow like 325 cfm What kind gen I heads have you guys used? and how much to convert to LT1 style cooling?

Having heads converted is kind of expensive. If i did i would go with brodix or dart though. But for a gm 847 cam you might as well just port some stock lt1 heads or get a custom cam because an 847 wont use the full potential of a head that flows 325 cfm.

Just like the other guy said, the GM847 is not that big for that flow, maybe a solid roller. If I went to the trouble of converting a regular sbc to lt1, I'd get 18 or 14 degree heads, and yes it has been done before with exellant results.

Just understand that big heads and solid rollers = rpm's which = spending money on the correct bottem end and valvetrain parts to make everything live. With that said, if your going to do it, do it right. I like the brodix 18x heads that have 18 degree architechture but use 23 degree valvetrain parts. They can flow up in the 320 range. Whether you use a big AFR designed for reverse cooling or a standard sbc head, you'll need to spend the same money on the other parts to make it work. The conversion itself only adds about $400 to the total.
