Yum. You could take a tooth or two out with those. Nice score, A91W!

a91what · Mar 16, 2019

Oh my promaxx180cc heads came in as well, let's unbox em.

xecute · Mar 16, 2019

Great stuff.

If I were you, I 'd have my machinist do a full disassemble and check for valve concentricty, and validate the installed height and spring loads of the valves. Often they are out, even on good heads.

Once thats done, re-prussian blue and bed in the valves to the inserts.

Common issues are the pushrod clearance and port positions. They don't have to be port matched if the intkae holes are bigger than your intake, and the exhaust holes are smaller than your headers. Engines make better power if the port mismatch goes that way.

The castings are good, but they do need to be checked. There is no such thing as a bolt on an ready to run set of bought in heads.

a91what · Mar 16, 2019

Yup, already on that, having some higher lift springs added so I can run a 1.7rr

Wow...180cc aluminum heads for 1000.00. They were almost twice that the last time I bought a set. Good on you.
Now there's nothing stopping you from making every single digit in your power goal.

1000.00?! HOLY COW i may need to order some of these when im ready to upgrade. get this thing going so we can get some feedback on them

KZGUNS · Mar 18, 2019

Was looking at those promaxx heads this weekend. Those ports look really good.

Anti_Hero0932 · Mar 18, 2019

sooo... wasnt there a similar brand that was pretty cheap but the valves and keepers weren't very good or something? im wondering how these compare

a91what · Mar 18, 2019

all stainless valves ect... I am going to have the machine shop swap the springs and retainers and keepers for a set of K800 springs

Anti_Hero0932 · Mar 18, 2019

Pro comp is the brand im thinking of. let me know how they work im wanting a good set of heads next once i get everything else going.

RangerJoe · Mar 18, 2019

I believe the promaxx heads are the old patriot heads if I am not mistaken. Off shore castings finished in the USA.

OK so i am still waiting to hear something about my block, but while i wait i decided to go ahead and price 2 differing builds... the first is the 351 the second is the 393....
I now have the heads to support either variant of the engine, my blower moves more CFM than either can use = blower will make boost....
I have to buy pistons/rings for both
-the cost between the two is very similar, within $200.. both aiming for a 9.5 compression ratio for the boost.

What direction should i lean? i cant decide.
351 OR 393

General karthief · Mar 25, 2019

More is better?
at what point will you destroy other things, the 351+blower will be plenty enough to destroy other things.

The first question you should find an answer for is how are you going to communicate all that power to the ground? Just spinning the tires without quickly going forward is a useless waste of rubber and effort.

a91what · Mar 25, 2019

Car already has full suspension underneath it with subframe connectors, team z upper and lower control arms adjustable rear shocks ect... it was able to plant all the power from the 306cid +12psi.... so im hoping the 393 +5psi will plant as well.

KZGUNS · Mar 25, 2019

Well you know what say. There’s no substitute for cubic inches. But seriously are there any negatives to the larger ci?

CarMichael Angelo · Mar 25, 2019

Rod angle and ring seal should be what you look at...a 393 has problems with at least one of those.

not sure... the rod ratio is 1.54 on a 393 with a stock rod... thats pretty close to the ls7 rod ratio and they dont seem to have any issues....

for those who are well informed on this stroker combo please advise

Anti_Hero0932 · Mar 25, 2019

393 would be bad ass.... but i have heard a lot of people beating the out of the tried and true 351 with no problems.

not sure on the machine process on the stroker with the block but a plus to the 351 is if something were to happen you could probably re use alot of the 351 parts on another run of the mill 351 and not be out all you machine work.

stanglx2002 · Mar 25, 2019

IMO is to stay simple with the 351 combo as it should provide less areas to be problematic. We dont want any blow-by, oil consumption, etc with the stroker, but thats just my opinion.
