Looks like im in the right place.

I know that Kaase makes a hemi head that will bolt to a 429/460. Can you put an original Boss 429 head on as well. I was told by a friend that it could be machined, but need to know for sure....Thanks Ted

Yes they will bolt on but you need to do oil system mods and drain backs.

Ted,the mods are fairly simple. I've done quite a few and if I can do them anyone can.

Im doing a 41 Willys, i know they didn't have a Boss Hemi in the day but i just can't build a Chrysler, got to me a law against it.....I have a set of heads and wanted to build a big inch Ford. Thanks alot....i will next need to find all the accessories for the heads as my original heads are bare.....BIg help....im going to stick around more on this site. Put alot of Cleveland and winsor stuff together, but all the big block stuff i have owned in the past were already built or didn't need built....I have a Mooningham Blower and Four Port Hilborn Injection saved back, do you know how hard it will be to find a blower manifold.....What a big help here....Ted n Vegas

Ted,you are building my dream machine . Each year when I go to the Hot Rod Reunion at Bowling Green,i drool all week over all the Willy's. Especially the ones w/bbf.

great knowledge base here with plenty of hp to back it up!if you are going to put the stock boss 429 heads on a non boss 429 block,then you need to weld up the stock o-ring counter bores in the heads.then you can use a stock type head gaskets.there is a member on here and the 460 forum that has done this with out warping the heads.for me,i had a set done and they warped .060,and had to have them straightend out before they could mill them.but in the end,they still had more than .050 milled off both heads any way,as the shops that did the work screwed them up.thats the biggest issue with the stock boss heads,and JUST GET THE RIGHT SHOP TO DO IT!.i have seen the stock boss 429 rockers hold up with big roller cams and street driven.i have a set that had mild porting and they flow 408 at .500 lift.

Check out this 41 it was a buddy of mines it had a 660 Thor headed motor in it then..

Damn That thing JUST LOOKS Nasty

Ok, Im alot smarter on these big blocks than i was two weeks ago, but still have some unanswered questions.....I have a 460 at the machine shop waiting for them to check out and see if it is any good. I have a set of Boss 429 Pistons for a blower motor, which i am going to run a blower.....I understand that the crank and rod distance are the same on a boss as a cj. But i cannot find the pin height any where from top of pin to top of piston.....The pin's in these pistons are just shy of 1 inch in diameter...I enclosed a pic of my Boss head, i believe they may of been opened up more, but not sure. as one is a 69 and the other is a 70, but have been CC'd to match.....will my pistons work with stock length rods....i read an article, where they used a 460 crank intead of a 429. Help Ted

have your machine shop check the comp height of the piston,rod length,and block deck height.thats the only way to know what you have and what you can use.you are going to use a an aftermarket rods and pistons for the boss heads?
