Yea canfield is a great head, you can get a stage 2 ported canfield for around $1400 that would sit great on top of your 331-347FoxBodyGT said:they are both quality heads, but from what I hear, the AFR springs arent' the best and it is rec'd that you replace them. Canfield Heads set up correctly may be a better value.
i built my 331 with the intentions of putting afrs on but i ran the stock heads for awhile and enjoyed decent power! Then i put my fully ported/valve jobed, c9 heads on and i have ran 12.32 all motor and on a 150 shot i ran 11.45 with a trap of nearly 126mph blowing the tires off. So it just goes to show that you do not need THE BEST heads to get a stroker to run. Would my car run better with a set of afr 205s? or canfields? OF COURSE IT WOULD! Can i afford it? HELL NO! im trying to get through college while having some car fun. Do what upgrades you can and listen to some of the more experienced ones on this site but do not let anyone tell you how to build your car! You have your own budget to work around so build it around that, be different! And in the end the car does what it doesBlk91stang said:Why would he go with a 306? Go with a 331 or 347 and enjoy some extra horsepower with the stock heads. Than when you have the funds go with a better set of heads and wake that motor right up. I'd personally go with a 331 just for my own reasons but the choice is up to you, either will make more power than a 302 or 306.
