I have a set of new afr fully cnc ported lt4 heads. They have upgraded heavier springs, have beed disassemled, hottanked and put back togather. They had lots of filings in them afrs are know for this. Thay are ready to bolt on, I have them in orginal boxes and have the build sheet for them. If seriously interested email me with a offer at michael_grayson496@yahoo.com. I paid 2,500 for these heads. also have matching intake for heads if interested.

 

what is the cc chamber in head to compute compression?
What lift will springs take?
