help me pick my heads???

[twdz28]

I am done building my short block 383 LT1 and now it is time to get a set of heads... Should I just go with a set of LT4 heads and have them Ported and Polished to the max or go with a set of Brodix 15* and have them machined to fit and set up for the reverse water flow... Oh and this is a custom grind cam so I cant give any spec on it… lets just say its large but would still be street able with a M6…

I like AFR aluminum heads. Personally thought I would talk to an engine shop to email summit racing and ask them.

scrap the LT1 and throw in a standard small block or LS1

[Deadcarny]

I would never scrap an LT1 for a GEN I small block unless I was building an All out race car and using a very expensive block (non-production block). The LT1 improved upon the standard Gen I in enough ways to make it an infamous engine within its 5 year run! There are LT1 production blocks out there running at the 1000 HP mark without issues, Very few production Gen I blocks can handle the stresses from high HP applications, hence the need for non production blocks. The LS1 is a different story...It's Head design alone reinvented the small Block platform and made the Gen I and Gen II look like a piece of ancient history!

ehy you know me man, i just dont like the opti, or the water pumps for that matter. but thats just my personal opinion.

[twdz28]

opti is not being used on this car... elec. water pump...

[89IROC&RS]

opti is the distributor, not the water pump. or are you switching to a different style of distributor ?

[89IROC&RS]

but my personal objections aside, seeing as they dont really apply, i would probly vote for the Brodix 15* heads as they have much more potential due to improoved valve angle. but your best bet is to compair the flowbench data from a group of potentially good heads and choose baised off that data. the manufacturer should be able to provide that information.

your kidding right??? i did not know the opti was a distributor!!! i better hurry and dig it out of the trash!!! lol, no but really i'm going coil over with a little package that me and a friend put together... i'll have more info on it later when we finish testing it...

[89IROC&RS]

Stock ported LT1 with some roller rocker will flow great number and save you a ton. I would stick with what you got

If you are putting the money out for some nice aluminum heads, (brodix), you should look into some AFR's. They flow a little better and provide a little more area under the curve from what I've seen.
