Im building an ls block with ctr pistons. I know this raises the crompesion quite a bit. The head will be ported and polished (stock valves) with crower 405 cams (the ones that dont require rocker mods) to a dual mikunni 45 carb setup. I know the carbs are different but what kind of horsepower and times have people done with this setup(on fuel injection). I am stuck on not using v-tech so what are my options as far as heads go? does anyone know how to eliminate vtech (like ericks racing did in their 87 crx)?
If i cant figure out how to do that i will oversize the valves on the b18b head and use nitrous. This is a temporary bottem end that i want to play around with until mine is built. Any help would be apreciated

 

b18b are non vtec, so no eliminating vtec, yes its no "h" in the vtec. VTECH is the phone

 

Sorry i meant eliminating vtec on gsr head. also the motor is going in a crx

 

the valves on a gsr i believe are the same size stock than the size of oversize valves for an ls head

 

ya but the overall length might be different between the heads i wouldnt know and the compression difference between the 2 heads are way different the ls head is bout 11.6 then the gsr head is about 12.6 maybe more. so u have to think about that

 

Well im sorry im jumping way ahead of myself. This is just a play motor straight ls block and head. Im building a different ls block that will be my quote unquote race block. that will have less compression and use heavy doses of nitrous. On that block i was considering eliminating vtec like aguilar did to save some ratating mass. i dont know im just throwing ideas around
