LTX damage report!

[kline454]

Well it looks like my days of stock heads are done (le3) , found that the deck of the heads where to thin after all the milling and failed on 3 chambers, wasnt the head gaskets like i was hoping, Time for some new heads, Whats the best option out the afr 227 lt4 55cc??So far thats looking like the best option i see, anyone else have a better option?

[Wooshie]

Not sure what your build looks like but the 227's require a monster cam not to mention CI to keep port volume up. These heads are usually saved for the most radical of builds.

comb was a .670 lift solid roller,385ci,le3, 12.1cr, we run the afr 227 on 383 sbc near same comb as my lt1 with good results,just wasnt sure if there was a better 23degree lt1 head out yet.

Thanks Tony, race or competition?is the extra port work really worth the $500???

Your car will love the race 227s. Sucks about the LE3s but Im looking forward to seeing what the new set up brings!:devil:

yes me to nothing is set in stone yet but thats the plan, bottom end only has a hand full of passes on it so replace the heads and go, I was very close to selling the bottom end and going with a ls engine but i think ill hold off for now....

If you can spend the extra $500 do it.

That would be an epic fail.

Find a set of AFR215 RR's have them converted and never look back.;)

[Nut]

Doesn't AFR make a set of 235's? Just convert them(like someone else on here) and they should work nicely :)

They do make the 235's that are hands down the best 23* head out there. But..................I can't tell you how much work it took to make them work on my 4.030 bore. :puke: . My valves are shrouded if that tells you anything. I would love to have a Bowtie race shop block with a 4.125 bore so I can un-shroud the valves on these heads. The 235's are made for a 4.125 or larger bore engine. I had to get a custom Cometic gaskets made for these heads.

It is better to stick with the 227's for our limited bore size. Or like Chris said find the old style RR215's

[Gumby]

RPM range, and valve lift must be determined in order to really select the best head.

[Badhawk]

Here's a couple other options I have been considering myself.

Brodix head hunter 229 heads.

There is a pair of AFR 215 RR's forsale on YellowBullet Brand new 1800.00. Thats a killer price I may get them and put my other engine back together with them.:secret:

Lol, no crap. Or me, hell I'd pay half :)

[Z8's]

Nope......................I've got a spare shortblock looking for a new topend.:secret:

[kline454]

Thanks guys

[Gumby]

All pro RR245

[Z8's]

The All Pro RR245 is a great head for a large bore smallblock it comes with a 2.180 intake valve.Personally it dont think that you can utiliize all the potential of that head on an LT1.

[Gumby]

But its a bad ass 23 deg head :D

If I was doing a 38-390 ish LT1 I would go with AFR 227 if I was going with an out of the box head. Might have to get some offset rockers unless you dont mind running the rockers pigeon toe'd.

[Speed Density]

I remember DiLuca had the first set of the 215RR heads, legiiiiiit.

[kline454]

Well after talking to Diamond about my pistons looks like the biggest valve i can go with is a 2.08intake so im going with the afr 210cc Comp. Eliminator cylinder heads. Will see how well it runs in the spring!!
