What type of intake and ignition system are you using?

For the money youd spend on heads & machine work to convert LT1 heads to SBC you can get Aftermarket aluminium that Flows way better for a few hundred more!!!!!! IF you wand an LT1 intake find a used TPIS Miniram!!!

Exactly...

While there are some very good LT1 heads out there, it is a short production run motor and the SBC has 10x the heads available. Most of the rotating assembly is the same...

Ill be doing it sometime next week. Paid $50 for heads, have new spring kit already, just drilled and tapped the heads to except my tourquer 2 sbc intake. Port matched. Going to cost me $50 in machinework. Done ill keep you posted

Itll cost 300 to match up ,weld, drill coolant passages on the LT1 to sbc or vise versa Drillin intake bolt patterns isnt all youve gotta do!!!!! Hell instead of doin all the extra work get an LT1 block & run a lot more compression on pump gas!!! Like 12.5 to 1 vs 10.5!! Or find large port Vortec heads & build MORE POWER! Money better spent in my opinion

I agree there is more to it than just drilling the heads for the intake, but what does the block have to do with running higher compression on pump gas? Unless your running the lt1 computer, you still can't run that high compression on pump gas. I'm not even sure you can do that on an lt1 operating system because it doesn't have the timing capabilities the ls1 computer has.

I have $200 in these heads including the new springs and welding/machinework..... Last i looked there arent any decent heads within even $400 of that price. Now granted i did everything myself, except the decking. Imo the biggest advantage of the LT1 heads is the 54cc chambers. No need to change pistons to bump compression on a non power adder engine.

Not sure if i read this correctly but many LT1 guys are running 12.5 to 1 comp. on pump gas with the stock lt1 computer. My new engine will be another.

The Reverse Cooling is what lets you get away with higher compression That & cam selection is the key I just dont see wastin money on converting the heads Unless they flowed 320cfm intake type of deal!!! Most well ported stock LT1 heads are lucky if they hit the magical 300+ cfm intake & 200+ cfm exhaust Really I think you need to study more Hell for 200 bucks you can get vortec heads that are a bolt one no mods type of deal for SBCs!!! Even if I had a 400sbc Id go with large port Vortecs Theyre alum... & 206cc intake runners IF youre gonna run a 350 block go with the LT1 in my opinion Unless ya wanna be period correct type of deal Stock LT1 alum... heads flow around 212cfm stock!!! Ported Dart Pro 1 200cc heads can do 311cfm intake!!!! you want 450hp or 600+ hp @ the crank!!!!!! Heads are where your power is made!!!!!!!! I will have almost the same money in my heads as my 396 shortblock Should be 650hp

I learned A Lot from my Uncle on the Circle Tracks of Indiana!!! Id rather use Sportsman II 200cc heads than LT1 heads on a SBC or Pro 1 heads if ya found em cheap Theres plenty of Iron Sportsman II heads on Craigslist for around the same money most people would spend on converting stock LT1 heads to fit a SBC!!!!!!!!

wow the fact i got the heads for 275 done, any why i have sold the tpi motor and im doing a full lt1

Thats a step in the right direction Good luck with the LT1 build A 406 TPI motor with Vortec heads & base is a pretty stout combo!!!
