Mismatched Heads

Other than looking funny, will this give me a problem? They are on a chopper, not a restoration.

Rich!---As long as the oilfeeds are the same & they drain thru the cyls. I see no problem running them!---Pay good attention when setting the manifold between them!--The less GAP the better & you want the gap EVEN!--No PIE-SLICES!.Use your plug set & check for even spacing!--Also a straight-edge across the 2 for lining-up the heads is nice to know what your dealing with & what may have to be compensated for!.--The o-ring spigot area on the heads should be the same as the manidold that your using!,--You don't want your clamps riding in from vibes & heat & cooling cycles!.If this works out,Your good!--The pic. looks good ,but pics. are deceiving -when you put the tools to it to check!---If you have outside oil-lines Make-sure to fit all now while the parts are not all in the way.--Good-LUCK!--its looking good!----RICHIE 8)

It looks like the rear is a 58 to 62 head. By chance does the front head have the outside oiler boss undrilled? If so this was a replacement head from way back. I am running the same combination only my repalcement head is on the rear. I always wondered if the replacement is FL or FLH but this has never caused an issue. It runs fine.

This engine was pieced together about a year ago in California and shipped down here to me in Texas. The builder used the best parts he had available. The fella I bought it from told me they were different year heads, I only noticed the heads looked different a couple weeks ago. Where should I look to check for the oiling tube hole? This is(obviously?!?)my first Pan.

Richard, take a picture of the other side of the motor. We will see it and other things that have been done with your motor. also what year is on the motor? looking at your picture again I see the front head fins are not the bigger style fins. It does not look like the replacement head I was refering to.

I don't see any outside oiler holes. As long as you use the James Blue head gaskets,& the oil holes are in the heads & the drains aren't blocked.I see no problem with Running the motor as is!/--Make sure the cyls. have the holes in the bottom,-By the looks of them I see no problems!./Have-Fun-----RICHIE 8)
