I suspect these to be old TFS intake and A-head from all the info I've read on here. Hopefully some one can confirm as there are no numbers on them at all. Got them at a good price I think, they have been sitting for 8-10years. different carb on the intake then in my other post and you will see why they were at a discount price, one damaged head. The deal rides on xray of the damaged head. Let me know about the ports as I'm sure they have been ported as well.
thanks guys for all the info

The heads are Old Ford Motorsport A460 heads, not sure what gen the intake is there was a Ford Motorsport intake then a TFS intake, and there is a newer gen of intake as well. Post some more detailed pics of the intake. The head looks to be repairable. Rich aka Boss 429 on here would be a good source to repair the head if you do not already have someone.

thanks for the clarity on the heads, I will have to get more pics of the intake when I get home next week. was there a big difference between the tfs and motorsport stuff? I should add they do have bbc exhaust, I have one more pic of the manifold,

There has been a bunch of revisions of the heads since first introduced the Motorsport castings can make a ton of power in the right hands. I run the same heads on my 528 prepped by Rich (Boss 429). The intake looks to be the Motorsport intake which is a little shorter than the first or second gen TFS intake, the newest version of the TFS intake uses a Windsor style waterneck.

well hopefully these were in the right hands at some point. see what the repair/engine shop has to say, I thought the ends looked like an old ford motorsports logo but seller said they were tfs. oh well hopefully i can post a proven build of my own here before spring. I found your build for the 523, is that the same one as the 528. Just wanted to see what you had done thanks

The 523 morphed into the 528. I had growing pains with the truck and all the additional power last year so I am building a car specifically to handle the power this year. I got in a rush last year and it bit me in the butt hard. Best pass was [email protected] which it hooked spun then dead hooked on and I guessed on the weight and was off by about 500lbs so the converter was wrong... You can tell by the mph it should have been a low nine second pass and it was 106° that day so it was down on power.

well the head has been checked, the bent exhaust valve wedged itself into the guide and cracked the aluminum there as well. for guides and seats and repair of just that one hole it comes to 1000 big ones.

seriously considering buying new now as I'm just guessing i will be around the 1500-2000 just for repairs and normal freshen up. I thought I was going to abandon them and then I got told even new heads will need to be dissasembled and inspected, so now I dont know.

Maybe if someone has been through the same deal I could sure use a "Ya thats about what I paid" just to make me feel better!

thanks again

No flow numbers or chamber cc's. I think I will get that checked before I make my decision as well. Good point. Around here they are 3200+ and that's for the 2.300 valve.

cc's-no flows numbers

Well I decided to keep the heads and have them repaired, brought the second one home and got out the burret, cutting board and grease gun! Intake ports measures 385cc, exhaust port measures 185cc and the combustion chamber is 72cc.
The shop that has them doesn't have a flow bench so just curious if a cam can be chosen with these numbers in mind or if I should send them out to another shop for flow numbers after.
I was thinking I would need a domed piston to get compression but now a flat top with my D9TE block might be okay? Any guesses? Any concerns of maybe too much being shaved off?

Thanks, Derrick

Should I get this moved to engine tech? How do I go about that


thanks

I know this is old, but it's mine:). Hypothetically speaking if there were two different size exhaust valves in these heads, 3 are 1.90 and then there was a 1.88 put in because that's all that was available. Plus one head was milled to 67cc and one was milled to 69cc. Is there some sort of +/- for that or should it be the same.
How much does 2cc effect CR and balance from left to right side. Also valve train geometry, different pushrods for each side? Or am I getting carried away!

Thanks crew

Hey Rich
That is what I would expect but when I asked the shop that did that work I was fed some BS about everything being done to industry standard! Then I was told when you start with junk you still end up with junk!
They came highly recommended too. I just can't imagine putting something together like that.

Would TFS have sold ferrera valves to a repair shop? They probably stock a little of everything but I wouldn't know. I got billed for TFS but they are definitely fererra.

Why are you so worried about the fererra valves? They are a good valve

I'm not worried about the quality. That's what's going in there to match everything back up.
I'm arguing with a repair shop about a job not so well done. The bill said TFS so I was not aware at the time that TFS used fererra in their stuff. I'm over that one, I should have phoned them before I asked that question. It is pretty insignificant but it all adds up. Right now I have two heads with different size chambers and both have at least one different size exhaust valve. It wasn't about me being cheap, I'm just a little frustrated that I have to pay twice.
The only thing they offered to do was grind the intake valve that they installed to match the height of the existing valves, not really what I was after.
I'm over it- it will get fixed
As of now I will let it go!

that's cool,make sure you moc up a piston in a block/or center test fit piston somehow in chamber before before you do anything,be a shame to see ya have to polish the chamber twice,and loose power because dome didn't quite match ,Ive seen this happen more then once in a build because of this. If you don't follow what I sayin, call me Ill be more then happy to talk you thru it
