Common, The bearing saddles have a groove, that helps offset the alignment issues.

Sounds like a 1g/6bolt head now.The casting number never has ment much to me, these heads get swapped around more than a SBC head.As far as having the 10mm corner exhaust studs, I get requests for that mod on heads, I have done 20 heads or so like that since the 2g E mani is better than the...

ProveIt, you called that one right! Seems the new thing I am seeing a fair amount is the wrong stone used in the cylinder bore. But that is a rant for another day.

I have built both the 4g and domestic V8 heads.What is used for seat widths on a V8 are not the same used on a 4g head.There is also more details to attend to with a 4g than a V8.

Your Killing me!!!I have too many projects now... and you offer this up!!You are a tease!!I am not even worried about the spare engine.... I have about 30 of them!Trade for a ported built 4g head?????? LOLBTW guys, If you think your DSM is a pain to find parts for, and...

Sorry, According to Ted, Engnbldr, he is out of stock on the STD size valves for about 5 weeks.He gave me that little bit of info last week.I honestly have lost count of how many sets of the BC springs I have installed. Not just in the 4g heads but EJ25 and sgte heads.

Make sure the valves have "6T" cast into the valve heads, both intake and exhaust.I just do not trust the parts store valves.Forget the HKS springs, the ones I have tested in the past are just weak. For less money Get the BC1100 this is my goto valve spring for stock and small 272 cam set...

Good deal, that makes the third one I know of on the market.I use the BC6103

So either you have 7 bolt rods in your 6 bolt engine with tons of rod side clearance, or someone modded the small end of 6 bolt rods to fit the 22mm wrist pins so they could hang the 2g/7bolt pistons.All 1g/6 bolts came factory stock 21mm wrist pinsAll 2g/7 bolts and the oddball 1g/7bolt...

I can understand the used H beam rout.But with a 6 bolt H beam the wrist pin is still 21mm, so it would still have to be enlarged to 22mm and have new bushings.But BC has a set of 6 bolt H beam rods with a 22mm wrist pin.I like those and have been using them in several builds.

They look like NPR piston modded by NRP for clips.Not a bad idea, but why hang cast pistons on H beams?Half the price of forged pistons, for half the strength?

I have been installing the BC1100 springs for 6?7? years, easy over 200 sets, I have never had a report back of a valve spring issue.So I say they are good. They work well with the smaller 272 cams, HKS, Comp/FP2, and the BC272Do not use them with the big 272 cams like the Kelfords, and...

If you are going to do valve seals, I would add new valve springs, ARP head studs, and oil port mod 1

The Fel-pro performance line of gaskets are typically a bit thicker, and have a better coating than the stock replacements.It is probably die cut from material that they use for the domestic V8 intake gaskets.They seal very well, and you will cuss if you ever have to remove it. It is like...

I have NIB BC 1100 Valve springs, they work well with the stock retainers. $95 shipped, fees included.I also have the good vition blue valve seals.
