Aftermarket Head

so i have been a big chevy fan for years and whenever i pondered about purchasing aftermarket heads i would just go to summit racing or an online store of the same magnitude and just look at the plethora of aftermarket heads out there like JEG, Summit, Dart, and Edelbrock just to name a few. my question is what is the import scenes equivalent to summit and are there any manufacturers like Edelbrock that actually make aftermarket heads for any of the vtec or even non vtec motors of honda?

Re: Aftermarket Head

Nothing really like that available in the import world. Everyone just uses a stock head w/ aftermarket valvetrain/port'n polish.

Re: Aftermarket Head

Yeah, the Big 3's families of small/big blocks reaped the benefit of staying in production in one form or another for over half a century, and they were shoehorned into everything. That huge market is why you can build a SBC entirely out of aftermarket parts.

Now, I've never been a part of this scene, but I believe that when people want to start making really big power with little Japanese I4's they just do everything they can to strengthen the existing block/head... Studs, gasket, girdle, reciprocating assembly... maybe sleeves, not sure, and stock heads get worked over on a flowbench.

Re: Aftermarket Head

The manifolds and heads on SBCs and their Ford counterparts left lots of room for improvement in design, unless you got one of the factory performance packages. They've gotten much better over the years, but the packaging on a V-8 still means compromises. One of the nice things about a straight inline engine is it's easier to set up a cross-flow cylinder head, and our stock head is pretty good. If you go to an engine builder who knows Hondas what you'll get is a port and polish job, optimized for the cams you're using. If you're on stock cams, that's not going to yield much, especially for the cost.

These engines are pretty highly tuned from the factory -- it's difficult to make much additional power with bolt-ons.

Re: Aftermarket Head

^^^this^^^

Edelbrock did make an intake mani to utilize the port an polish, not 100% on if it was for the B-series block or the H-series. Also those heads you refer to have valve lifters and push rods, extra measuring and adjustments with the rocker arms. The common honda owner doesn't need to fudge around with whether 1.6 or 1.7 push rod to stop valve float or piston slap. You can get away with stage 1 tuning and valvetrain upgrades. The thing you need to look out for is the timing belt. No chain in there, and they need to be changed about every 60,000 miles.

If you know already, you are 1000% in a better place.

The Honda owner who does is very uncommon indeed, since our overhead cam engines don't have pushrods! :)
