Description
The Best 20° In-Line Head You Can Buy! - Information below is referring to fully assembled heads.
AFR's BRAND NEW 220cc Renegade Ford head is a fresh addition to the lineup that adds quite a punch to our already formidable and proven 20° Ford Heads. These new 220cc heads flow a massive 340 CFM, averaging an 11 CFM increase from .200-.800 lift over our previous best in spite of its 5cc smaller intake runner. This is the best small block Ford 20° inline head you'll find to provide huge horsepower to out run your competition. With the largest intake and exhaust runner volumes for our in-line Ford line up, these are the ultimate for NMRA Renegade or Hot Street classes. With lightweight 8mm 2.100 intake valves and 1.570 exhaust valves these heads move massive amounts of air. Combustion chamber volumes are available in 58cc or 72cc. 80cc exhaust ports and bolt pattern are raised .375 (3/8") higher than stock, this rarely affects header or chassis fitment. AFR's new 220cc is the perfect choice for 347 through 427 CI windsor engines operating from 4500 rpm upwards. AFR's trademark 3/4" thick cylinder head deck makes them ideal for heavy nitrous or blower applications.
Note:
2.100 valves will require aftermarket pistons notched for valve clearance.
