help me pick my heads???

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.

they do a great job!

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

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.

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

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

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...

lol ok ok i get the point you know the difference, i just wasnt sure geeeze ;)

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.
