Procomp Complete Assembled CNC Aluminum Cylinder Heads 64cc

SKU: PC3041


Description:
CNC Porting- Combustion Camber, Exhaust and Intake Ports all fully CNC Machined!! CNC machined piston and combustion chambers offer superior control over flame travel and a quench area, and allow easy and accurate duplication of reverse and positive domes CNC ported heads eliminate human error and variation from port to port that is commonly found in "HAND PORTING". Unsurpassed repeatability from one cylinder head to another. Combustion chambers are exact in volume - so every cylinder has the same compression ratio. Each port is exactly the same cfm - so every cylinder can reach the same power potential. Each port is the same cross section - so every cylinder can reach its true RPM potential. CNC machining produces ports and chambers to within tolerances of no more than .002".

I had a friend running them in a 2900 lb coupe 360 ci windsor with a glide, his car went 6.70's in the 1/8. I hear you should have a professional check them for defects and assembly issues.

they are ok,ive seen a set box stock from ebay flow 285 or so and with a good valve job flow 307 same head.
biggest thing is what valves and hardware is put in them.
i think theres a guy closeby to you in carlisle that sells these.
ill ck with my friend.
