cylinder heads flow
Today I was checking a bit at the cylinder heads and if something was new in the market since I last looked at the heads.
I was comparing flow charts of Edelbrock e-street, Edelbrock performer rpm, Brodix IK180 and Bleprint H8002k heads. I was stumped at how the edelbrock rpm heads have the same flow rate or even worse flow rate than the cheaper e-street heads. Brodix and Blueprint are almost the same. What the heck are you paying for in Edelbrock RPM heads?
What should I look at in the $1000 +/- 20% ball park? Are there any recommended heads in that price range?

The Edelbrock E-Tec heads appear to be the only Edelbrock head worth considering.
Profiler heads are loved by many building budget engines.
Remember that flow isn't the only number that matters.

$800 you cant go wrong. Honest seller, hes been around a long time. Id use these in a hot second over some overseas junk.
Looks like your wants wiht costs shipping prohibit you from doing better than some cheap chinese ebay heads
Id say grab these as quick as you can. Nothing to do excpet put them on. Cost a lot more than hes asking to do all this
You can make an easy 400+hp with these and keep good manners.

Youd get a bump in compression and a nice boost in power.

You want to shoot for 180cc ish on the intake runner size.
If you were in the US, I'd say to wait for the holiday weekend sale this weekend and pickup a set of the Jegs (rebranded Profiler 180cc) heads here: https://www.jegs.com/i/JEGS/555/514002/10002/-1 but import duty from the US will probably be painful.
Being in an EU country, you can take advantage of the EU and Mexico's reciprocal tax agreement and buy a set of heads from an online performance site in Mexico and avoid import duty.
Last I checked, Autozone.com.mx carries Edelbrock heads.
If you don't mind paying import duty, then the world of options becomes available.

Are you going to run a flat tappet or do a retro hydraulic roller conversion cam? (You'll want to make sure that new heads come with springs appropriate for your cam choice; I know, because I didn't and had to buy new springs, retainers, locks, and seats.)

$1,741 with 7/16" rocker stud + tax + shipping + customs into the EU == way over his budget.
At $1,000 +/-$200 he's looking at Chinese, Profilers via Jegs or Summit Racing for $1,000 on sale +import duty, or those $800 reworked C4 heads on the C4 forum that Cuisineart pointed him towards. -My understanding is they flow about like Vortecs but are aluminum and have been fully checked out by a professional shop. -With a private person to private person shipping, he might get lucky and not get pulled for Customs Duty, but I doubt it.

Oldie but a goodie; you'll have to track down the new head's owners and names in many cases, though: https://www.hotrod.com/articles/ccrp...head-shootout/

Chad Speier Racing's 210cc Profiler Heads fully assembled are $1,550 + shipping and those FlowTeks are $1,800, but +15 CFM @ 0.600" improvement. The min CSA of that flowtek is actually smaller than the Profiler 210cc (2.15 vs 2.19"), too! (Avg CSA obviously slightly larger). The FlowTek is also CNC vs cast... I am just shocked at how much those things flow!

Every company wants to make money... Blueprint is no different... yes, they will compromise on heads to make themselves more money 100%
Cheap, fast, reliable... choose 2..*
my engine has about $13-15,000 in it... its fast and reliable... I can smoke a C7 and any C6Z ZR1.. Crank alone was over $2K.. will blueprint put in a Calies Dragon Slayer Crank in for you at that PRICE... think not:-) .. why? because they want to make money...*

Shipping to Slovenia from the U.S. is crazy expensive. Don't even bother with the 113 heads in C4 section. Buy something form an EU based company website. Amazon.it has Edelbrock heads starting around 850 euros each.
