I cant find a original steel head gasket .015 thick so I had to go composit and its .041 so I,am considering cutting off .010 from the deck and same from the head surface . got a offy 4bbl alumin intake and a 500 cfm holley 2bbl new carb also for it.

Sounds like a good work build.
It could use more cam but if you already have a new stock one, you dont want too much cam for your use anyway so probably fine.

I think the lumps would help because they would help velocity and mixture quality for everyday, and add some power too without the lope or gas eating qualities of a big cam.

A 4bbl carb would help, better gas mileage than that big Holley 2bbl. A 500cfm Carterbrock would be about perfect, or a 390 Holley 4bbl or even a 4100 Autolite 4bbl, 440-500cfm.

Remember that 500cfm Holley is really only about 350cfm measured by the 4bbl method.

DECIDED TO CHANGE MY SETUP A BIT. I built a 250 cylinder head about 12 yrs ago and never used it in fact i forgot I even still had it until I got into the 6cyl head frame of mind ! (getting old is tough LOL) so my head choice is now a mildly ported 250 that has 1.94 int & 1.60 exh swirl polished necked down stem stainless valves and chambers slightly relief cut & polished to inprove flow of the bigger valves. it has the bosses in the intake ports removed so I,am gonna buy some lump ports for it. sure hope them lump ports dont come loose over time ! it also has screw in rocker arm studs. since the cc's of the chambers are larger I had th head cut .010. found a n.o.s. GM 292 steel head gasket. I think I,ll also cut the top of the block down to .005 deck height to help with compression. OH yeah I found a almost new 390 holley 4 bbl /electric choke #8007.

I am 77 and would never forget I had a head like that !! Sounds like you are going to end up with a nice motor...J

been spinnin wrenches since 1965 and with time you forget alot of whats in your parts stash. boy prices sure have gone up in this time frame >>>>>>

GOT MY HOLLEY 390 CFM/ ELECTRIC CHOKE CARB TODAY. NEVER HAD A HOLLEY THIS SMALL BEFORE. SEEMS LIKE A TOY ! LOL
