What up? I have the older svo GT40 aluminum heads and was wondering if its worth the time and effort to port and polish them. Also the same with the GT40 intake I'm running. I have a 306 under them but I'm hoping to get a 363 within a year or two. Any advice would be appreciated.
Not worth it.
Sell them and buy a much better set for a 363, like afr 185's or CNC twisted wedges.
Dump the intake too for an edebrock rpm II or victor jr.
