440 Source Big Block Alum. Cylinder heads

I bought a pair a while back but havnt installed them yet.
I did alot of reasearch because i can only do it once on my budget.
From what i found these heads are good for price and for a good 10-12 second car. In my opinion if your running a 8-9 second drag car you have enough into your car where everyone knows its not stock... meaning the stock port location and absence of edelbrock logos part dosnt matter...
And if you have the money and means to get your car that low in e.t. i wouldnt skimp on heads anyway,
I bought them because 400 dollers in savings made the differnece of purchesing heads or not... no matter what you should get them checked out.. and with everything theres no guerentee they will last a week or forever. Theres alot of people with low e.t.'s that ran there heads,stroker kits, and so on with no problems for years.
Overall take everything someone says with a grain of salt and go with your gut. I have no ties with this company and im not defending them because i can care less but all and all theres alot of people that are afraid of chinese japanese and all that when you use there products and trust your life with things made there more then you know it.
My 2 cents
