Sorry, but we're way too swamped with work to be running sales .

That said, we're not building much margin into our pricing on these services, so a sale wouldn't make sense anyway.

Thanks

Sorry if this has been asked, but I was wondering about opening the heads up even more for bored blocks. If it makes that big of a difference to open a 2.0 head to a 2.5 then I would think that 2.0, 2.2 and 2.5 would see benefits for the head being properly sized to the bore. Have you tried this? If you have, does it make a difference? I'm sure that a formula could be figured out. Seems like this could be a nice deal for people who bore their 2.0 2.2 and 2.5 blocks to over sized pistons.

Example, I have a 2.5 Sti block that I am building for a hybrid set up and I have a set of Cp 100mm pistons to go in. Instead of opening the heads up to a 2.5 could you opening them up an additional .5mm to match the bore of my block?

That extra .5mm I very small and I doubt it would make much of a difference. We use 100mm pistons in most of our builds and they work very well with the 2.5l chamber.

We're getting these turned around in 2 weeks consistently.

Thanks

should the heads be decked and valve seat grind completed, then send the empty heads for cnc?

I'm having a shop rebuild my 2.0 into a 2.5 bottom, 2.0 heads. I prefer they perform all head work except the cnc. Part of the issue is down time to outsource the cnc...how can the 2 weeks be shortened?

I would do the CNC first, then have your shop do the valve job, deck, cleaning and final assembly.

Sometimes we can get them turned around quicker, but can't promise it.

Payment is taken when we receive the heads from the customer.

Thanks

what level of boost could you run safely without linering, I understood 25psi/1.72bar.

I've run up to 30psi on the stock sleeves, but I wouldn't expect that to be reliable indefinitely. 25-27psi should be nice and safe assuming everything else is in good shape.

Any chance of you guys starting a purchase/core return service? Being in PA I don't get a warm fuzzy feeling sending my heads out to cali and then waiting but if I could just purchase the already machined heads and send in mine as a core that would be great. Understanding of course my heads would have to be in a condition equal to those being purchased etc....

I'm guessing there would have to be around a $1K core charge. Would you be cool with that?

Exactly correct. We would have to be able to replace the cores in case yours were no good and it's not easy to find good used cores. The other problem is that a lot of the 2.0 heads develop small cracks around the spark plug port, so I doubt we could keep cores in stock. The other part is that different people choose different services to go along with the CNC work so things could get complicated. We're always happy to provide brand new castings if you'd like, but obviously you have to pay for them.

Thanks

hey i had a quick question for you guys, will the $400 service with the grind match the chamber match the ej257 shortblock's so that the little edge's heat on the heads does disappated properly? the major flaw in hybrids and why they're so unreliable and ringlands tend to blow.

^ I think that is the primary purpose of the combustion chamber shaping... it removes the lip/edge from heating up. They also shape it to the 257 heads at the same time to match/mate correctly with the ej257 block.

Correct... the main reason is to get rid of those sharp edges. The secondary reason is to bring the compression ratio back into factory spec for an EJ257 longblock.
