We are putting the TF Twisted Wedge Heads on my 302. I have 3 questions:How much torgue should the head bolts have? How much torque on the intake manifold? How much torque on the headers? If there is anything else we should be looking for, please let me know...

Don,I don't want to steer you wrong so I'd call TFS and ask them. It's been awhile since i've done it and can't remember exactly. With the header bolts you'll be lucky if you have room to tighten them with a hand wrench. I think it was 3 step torque with stock numbers for the heads. 20-22 ft lbs for the intake and just hand tight and then about another turn for the headers. I used anti-sieze on the header and intake bolts. I had a problem originally with the stock intake bolts. The intake didn't line up perfectly with the heads and the bolts weren't long enough and I cracked one of the stud bosses. It cost me about $80 to fix it. Next time around I used slightly longer intake bolts and slightly enlarged the intake bolt holes. Good luck. quote: Originally posted by Big D: We are putting the TF Twisted Wedge Heads on my 302.

please retorque the head bolts after your engine warms up and cools down. i think this may be the reason my motor is blowing out steam from the exaust when i get hard on the throttle. my heads are new afr 165's and i used the gasket afr recomended. ford small blocks are prone to have head sealing problems in high horsepower and high cylinder pressure situations. aluminum will have different expansion characteristics than the cast iron block its bolted to and its unlikely that the aluminum will crush the stainless steel rings around the cylinders in your gasket. i plan on calling felpro to check to see if they agree with the gaskets afr recomends.------------------ 67 coupe, 650dp and rpm intake on 5.0 with afr 165 heads, 4 speed, 4.11's.....best so far is [email protected] in 1/8 mile with 1.91 60ft. time.

Yes, We already found that out... I wish I would have posted earlier... We weren't sure what length we needed, but found out from Summitt... Hey you guys,,, Thanks for all the input... Like the old saying goes,,, "It is better to be safe than sorry"... The guy helping me is very knowledgable, but he is a chevy guy and it is always good to get more input... It's appreciated...
