AFR 185's on stock shortblock, pv clearance?

I've got a stock 95 L shortblock and am currently running
small valve Ebrocks I got quite reasonable.

Upgraded to a .538/548 lift cam with .222, now would
like to go AFR 185's for a future increase to 393.

Anybody know if the 2.02's in the 185's would clear the
stock dished pistons? Or if not, if very much has to be
notched out?

Thx!

I've searched on here for the same answer and it's NO, the pistons won't clear using the 185's. I've heard of a small cam & 165's having interference w/95 5.0L on here

185s are not going to get the proper flow on a 393.

I'd check piston-to-valve just to be sure.

This is not a 5.0 liter. This is a 5.8. Deck height is different. NLOC has the answer.

I would check the clearance. Certainly after I pulled the stock iron GT40 heads, ie. small valves, off of this completely stock 95 Cobra R engine (about the same as Lightning but 1.7 rockers) and found this:



Don't know what the hell they did to cause it (missed shift or wrong downshift probably) but I sure don't take clearance lightly anymore.

1995 Ford Cobra w/IRS, white - Coyote swap with full MM front end in progress.
1994 Ford Lightning, red - HCI and Kooks in progress.
1993 Lexus LS400, grey - stock
2003 Infiniti M45, black - stock

185 afr heads will clear fine on a 351 engine roller or non roller, I've done both. It will be close, but since your chances of a missed shift or few with an automatic, you'll be fine until you stoke your engine, in which you'll be changing pistons anyway. While true that 393 and 408 engines struggle more to breathe, the 185's will do fine unless your going really radical. Then the 205's would be better.
