Here is the thread of 65Fast's issue, which sounds just like your problem. I'd be pulling the heads to inspect the valves to ensure they haven't hit the pistons....as was the case in 65fast's case. http://www.stangfix.com/testforum/index.php/topic,7667.0.html

I believe my dual roller was a Cloyes brand. I had clearance issues with the fuel pump eccentric and the timing chain cover, but mine must have been a fluke cause I hadn't read about it happening to anyone else.

Well, ive decided to bite the bullet and have the engine completely rebuilt. Its been burning oil pretty bad for a while anyways. The guy in town who has built Fords for 30+ years said he would do a complete stock rebuild for around 1200 which seems pretty reasonable.

What im wondering is: should i have him clean up the exhaust ports on the stock heads? when i mentioned porting the stock heads to him he got a funny look on his face and basically said it would be a waste of money because there is not much to gain. But ive also read from several places that the exhaust ports being done makes a considerable difference...

Also, while this car is my daily driver, i think a little more pep in its step wouldn't be a bad thing. Would it be ok to add a little more cam considering we will be reusing stock heads? The only things that are not original on the engine are the intake: weiand action+/carb: holley570/headers: headman elites/ignition: ignitor2,flamethrower2.

Im sure ill have more questions later, but feel free to throw out some advice. im in the process of pulling out my engine to take it to him and im taking my time because he wont be able to start on it for 2 weeks. So in the meantime and advice/tips would be much appreciated

Ryan (monkeystash) has ridiculous knowledge with numbers and different combos. I'd say bump the cam up a little and go for the porting. If you're gonna get into some head rebuilding you can get some aluminums pretty reasonable. I've also got the 302 heads I was using, before the upgrade, sitting in the basement that have maybe 1000 miles on them.

Well i guess i dont have to reuse the stock heads. Its always nice when your mom is friends with the owner of the business and he lets you open a PO for the rebuild. so many options now... :$$$

I would have him replace the valve seats while it's down.

I used the Comp 268H with stock heads and it ran pretty good.

As for heads, don't tie up money in stock heads. I am using 289 heads that I had the exhaust ports cleaned up, hardened exhaust seats, stainless 351 valves, new valve guides, and screw in studs. When it was all said and done I was into them over $800, and that was a friend who owned a machine shop doing the work at a discounted rate. You can pick up some low end aluminum heads for that that probably have larger valves and they'll flow better out of the box.

Exactly. You can get aluminums for under $1000.

Don't forget you probably have a fuel issue!

Agreed, just try to keep any performance upgrades on the "low" side. With a daily driver, you don't want to "over-build" the motor for it's intended use.

LMAO, just like a crackhead does not want to carry a pipe all the time.

You can overbuild and not hurt a daily driver, you just have to convince your foot to not mash down so hard :ecit

My 289 I had in a late model Mustang got very good MPG on the highway but around town it was too much fun to kick the 650 DP open and rip through the gears from light to light :)

Now if by overbuild you mean stuffing a cam in that makes it lope like a top fuel dragster, I agree.
